Haddow, Sarah Louise. "Perylene derivatives and silicon nanosheets." Thesis, University of Nottingham, 2017. http://eprints.nottingham.ac.uk/41873/.
Full textAbstract:
The work presented in this thesis explores two different topics of interest, firstly a synthetic project fabricating small building blocks for supramolecular arrays. The building blocks are a series of perylene monoimide monoahydride (PMIA) compounds, synthesised by a four step process. The PMIA compounds belong to a family of dyes called the rylenes which are known in literature for their optical properties and use in optoelectronic devices. Chapter 2 begins with the description of the synthesis and characterisation of these molecules, where Hirshfeld surface analysis is used to investigate the solid state intermolecular forces between adjacent molecules. This is followed by the details of connecting two PMIA through organic linkers and it explores the structural and physical properties of the so called dimer. The physical properties investigated include, optical and electronic properties utilizing spectroelectrochemistry, cyclic voltammetry and electron paramagnetic resonance techniques. The chapter also explores the asymmetric feature of the building blocks with the aid of X-ray crystallography. The second topic of interest is silicon nanosheets (SiNS). There are many types of these two dimensional (2D) materials published in literature, however one type which has had minimal attention is a buckled sheet structure known as layered polysilane. A synthetic and structural investigation into layered polysilane and closely related siloxene, are carried out in Chapter 3, identifying their bonding arrangement and topographic assembly through a range of analytical techniques. Like many other SiNS, it is proposed that this material can be used in nanotechnology devices in the future, and this thesis makes some way towards identifying the structure which is important in order to use them in such devices. Chapter 4 leads on to discuss the investigation into the modification of SiNS fabricated in Chapter 3, via a range of small organic molecules. This is another area in literature which has great scope for investigation and exciting potential for use in nanodevices. An important difference once the SiNS have been functionalised with small organic groups is their enhanced solubility, in comparison to being insoluble before functionalisation. This opens up a wealth of applications which require solution phase activity. A range of surface analytical techniques aid in identification of functionalised sheets and Chapter 4 details the challenges and successes.

Full textAbstract:
This thesis deals with exciton relaxation processes in thin polycrystalline films and matrix-isolated molecules of the perylene derivatives PTCDA (3,4,9,10-perylenetetracarboxylic dianhydride) and MePTCDI (N,N'-dimethylperylene-3,4,9,10-dicarboximide). Using femtosecond pump-probe spectroscopy, transient absorption spectra, excitonic relaxation in the lowest excited state subsequent to excitation, and exciton-exciton interaction and annihilation at high excitation densities have been addressed. Transient absorption spectroscopy in the range 1.2eV-2.6eV has been applied to thin polycrystalline films of PTCDA and MePTCDI and to solid solutions of PTCDA and MePTCDI molecules (monomers) in a SiO2 matrix. We are able to ascribe the respective signal contributions to ground state bleaching, stimulated emission, and excited state absorption. Both systems exhibit broad excited-state absorption features below 2.0eV, with dominant peaks between 1.8eV and 2.0eV. The monomer spectra can be consistently explained by the results of quantum-chemical calculations on single molecules, and the respective experimental polarization anisotropies for the two major transitions agree with the calculated polarizations. Dimer calculations allow to qualitatively understand the trends visible in the experimental results from monomers to thin films. The broad excited state absorption band between 1.8eV and 2.0eV allows to probe the population dynamics in the first excited state of thin films. We show that excitons created at the Gamma point relax towards the border of the Brillouin zone on a 100fs time scale in both systems. Excitonic relaxation is accelerated by increase of temperature and/or excitation density, which is attributed to stimulated phonon emission during relaxation in k-space. Lower and upper limits of the intraband relaxation time constants are 25fs (resolution limit) and 250fs (100fs) for PTCDA (MePTCDI). These values agree with the upper limit for the intraband relaxation time of 10ps, evaluated from time-resolved luminescence measurements. While the luminescence anisotropy is in full accordance with the predictions made by a luminescence anisotropy model being consistent with the exciton model of Davydov-split states, the pump-probe anisotropy calls for an explanation beyond the models presently available. At excitation densities 10^(19)cm^(-3), the major de-excitation mechanism for the relaxed excitons is exciton-exciton annihilation, resulting in a strongly reduced exciton life time. Three different models for the microscopic behavior have been tested: a diffusion-limited annihilation model in both three and one dimensions (with diffusion constant D as fit parameter) as well as a long-range single-step Förster-type annihilation model (with Förster radius RF as fit parameter). For PTCDA, the latter two, being structurally equivalent, allow to fit a set of multiexponential decay curves for multiple initial exciton densities with high precision. In contrast, the three-dimensional diffusion-limited model is clearly inferior. For all three models, we extract annihilation rates, diffusion constants and diffusion lengths (or Förster radii), for both room and liquid helium temperature. Temperature dependence and orders of magnitude of the obtained parameters D or RF correspond to the expectations. For MePTCDI, the 1D and the Förster model are in good agreement for a smaller interval of excitation densities. For a initial exciton densities higher than 5 x 10^(19)cm^(-3), the 3D model performs significantly better than the other two.

In this thesis, we studied a series of perylene diimides bearing an aniline substituent, namely Di(2An)PDI, Di(3An)PDI and Di(4An)PDI. Previous studies showed that the aniline substituent could undergo electro-polymerization reaction. Electrochemical and UV-Visible experiments show that Di(2An)PDI, Di(3An)PDI and Di(4An)PDI can be successfully electro-polymerized onto Pt, GCE, ITO and Au electrode in CH2Cl2 solution. The optimal conditions of electro-polymerization for each compound are investigated.

This research mainly is the discussion to take perylene-3,4,9,10-tetracarboxylic acid dianhydride as a main body. Alkyl derivation caused its two sides to produce the different number of function groups. And they are deposited on ITO substrates and used the same metal electrode—aluminum. This is probing for Schottky barrier heights relation between the metal. Perylene derivatives were decided by Fourier Transform Infrared Spectroscopy and the Nuclear Magnetic Resonance Spectroscopy.The former examined its including specific function groups and the latter examined position of hydrogen spectrum. After organic vapor phase deposition, they were detected the atlas by the Ultraviolet Spectroscopy which obtained approximately about 2 eV to calculate the energy gap of perylene derivatives. The voltage and the electric current were produced by the Source Meter, and Schottky barrier heights calculated.Using X-Ray diffraction to calculate distance of crystalline. According to experimental demonstration, Schottky barrier heights of perylene derivatives were obtained approximately about 0.79~0.90 eV. The two sides of branched chains for perylene derivatives were alkyl with linear chain. Schottky barrier heights decreased from 0.90 eV of N,N''-diethyl-3,4,9,10-perylene-3,4,9,10-perylene tetracarboxylic diimide to lowest of N,N''-dihexyl-3,4,9,10-perylene tetracarboxylic diimide. The number of carbon increased to seven, and Schottky barrier heights increased again. And the distance of crystalline decreased from 14.56Å to 7.5Å, and then the distance of crystalline increased again. Size of smectic layers between perylene derivatives effected size of Schottky barrier heights. It is not easy to occur for the large crystalline distance which was caused that π-π interaction.So Schottky barrier heights became larger.

The two main-goals of this thesis were achieved. Well soluble acene derivatives for spin-coated TFTs were obtained, showing charge carrier mobilities in the range of polymer p-type materials. Novel core-fluorinated perylene bisimide dyes were synthesized particularly and the use of electron deficient substituents lead to PBIs with outstanding air-stable mobilities in thin film transistors prepared by vacuum deposition techniques. The relationship between performance, air stability and solid state packing was elucidated in detail by single crystal X-ray diffraction analysisDas Ziel der vorliegenden Arbeit war die Synthese verbesserter organischer Halbleitermaterialien, detaillierte Untersuchungen ihrer Moleküleigenschaften sowie ihrer Packung mittels von Röntgenstrukturanalysen von Einkristallen sowie die Ableitung von Struktur-Eigenschaftsbeziehung mit Hilfe der Ladungsträgerbeweglichkeiten in Dünnschichttransistoren.

Abstract This paper studies the subject of discussion by the laboratory synthesis of five different N-benzyl Perylene derivatives for organic thin film transistor active layer materials and by the Fourier transform infrared spectrometer and UV / visible light absorption spectrometry materials Structure and properties. The experiment is divided into two parts, the first part we will five different N-benzyl Perylene derivatives deposition thin film in the bottom contact (Bottom contact) structural elements, we compared the substrate film at room temperature and the different annealing temperatures Comparative analysis of electrical components differences. The second part we will different N-benzyl Perylene derivatives of the film deposition in the ITO glass substrate analysis, using absorption spectra and fluorescence excitation spectrum of research is different N-benzyl Perylene derivatives Films of differences. In the first part of the initiative, we found that film-forming material for after annealing treatment, electrical components have increased as the annealing temperature to enhance the trend. And active layer materials in the substrate film annealing temperature at 180 ℃ for the electrical components of the active layer than the film-forming temperature for the substrate at room temperature and confirmed the excellent electron-withdrawing group effect and three-dimensional obstacle is contained and will also enhance mobility. The second part of the absorption spectra we found that thin-film structure with the DDP of two sides connected on functional groups, these results in the absorption spectra to produce long-wavelength red shift and through software analysis for molecular π-π interaction of the absorption spectra also found with the annealing temperature increased to 220 ℃, the spectral red shift will be. Fluorescence excitation spectroscopy (PL) in the part, we found that PL peak shift of signal will have an impact carriers mobility, which is due to the molecular stacking process in the substrate, because of substrate materials and organic materials of surface energy not match, leading to the molecular stacking during the stress caused by the emergence of intermolecular, further produced a large amount of defects in the film of junction position, the transmission carrier capture by defects affect the carrier mobility.

In the thesis we designed two series of n-type electron transport organic semiconducting materials. A detailed studies on their synthesis, optical, electrochemical properties and field-effect mobility has been carried out.We have successfully synthesized a series of perylene bisimide and anthracene derivatives with substitution of electron-withdrawing groups. When benzimidazole attach to anthracene and perylene, it renders the materials become very insoluble in most organic solvent. To improve the solubility, we introduced long carbon chain into the framework of the benzimidazole group. The structures of the materials are shown in the bottom. We employed DFT and semi-empirical methods to compute the molecular orbitals of the compounds. The HOMO and LUMO energy levels were experimentlly derived from cyclic voltametry (CV) data. The optical properties of absorption and emission were explored by UV-Visible and fluorescence spectroscopic methods. The heat stability were determined by TGA (thermogravinetric analyzer). Some of them are further characterized by single crystal X-ray analysis.

In this study. We use 3,4,9,10-perylenetetracarboxylic dianhydride（PTCDA) and 1,4,5,8-naphthalenetetracarboxylic dianhydride（NTCDA) as our main structure. Due to n-type semiconductors are not stable in the air, we introduce the perfluoro-alkyl chains into our structure (PTCDI and NTCDI), anticipating that these organic semiconductors are more stable in the air. Here we prepare a series of n-type organic semiconductors based on perylene diimide and naphthalene diimide with different perfluoro-alkyl chains, conferring the numbers of fluorine and the distance from the core. Finally, we systematically investigated the effect of chemical structural variation on molecular level, electron mobility, and transistor stability.

In order to develop more air-stable N-type materials applied to Organic Field-effect Transistors(OFETs), we have designed a series of asymmetric Perylene Bisimides (PBIs) with molecule’s two imides modified by alkyl chains and perfluoro-alkyl chains separately, then investigated their electron affinities、stacks in solid state and thermo-stability, etc. Furthermore, we also fabricated three new PBIs on OFET devices under various conditions, used XRD and AFM to probe crystalline packing or film morphology of semiconductors. After experiments and measurements, we found that all three compounds have higher reduction potentials than H2O(-0.658 V vs SCE), that’s a desirable quality for air-stable N-type materials. As for devices, through XRD and AFM we have observed that better crystalline or morphology of semiconductors generally formed when materials deposited on OTS- or ODTS-pretreated substrates under 125 ℃. In rough, C4H-PBI-C4F and C8H-PBI-C4F have better device performance, both two have highest carrier mobility up to 10-2 cm2V-1s-1 and the best Ion/off 104 of C4H-PBI-C4F devices. Basically, most devices fabricated with three PBIs could exhibit good electric performance under air. Moreover, after 12 months stored in air, the carrier mobility of C4H-PBI-C4F or C4H-PBI-C8F devices have not declined, but both their Ion/off ascended. Similar phenomenon also appeared on C8H-PBI-C4F devices, which had proven excellent OFET performance and stability of three materials under air.

This study employed a chloro-substituted perylene diimides derivative (Cl-PEPTC) for the formation of self-assembled single crystal micoribbons by solvent exchange method. Transistor devices based on a network of Cl-PEPTC microribbions have showed typical n-channel field-effect behaviors. The extracted maxima mobility was 1.05 × 10-3 cm2V-1s-1, threshold voltage was 68.3 V and on/off current ratio was 4.74 × 104. The devices were further measured under three different conditions: (ⅰ) glove box, (ⅱ) ambient air (relative humidity 50 – 60 %) and (ⅲ) high humidity environment (relative humidity > 90 %). After 80 days, the transistor showed a remarkable stability. The on/off current ratio still maintained in the order of 103. The reason of transistors degradation is probably due to that the hydroxyl group formed at the semiconductor/dielectric interface trapped and captured the electron carriers. In order to investigate the potential application of Cl-PEPTC field-effect transistor, three commercial white, red and green LEDs were employed for photo response behavior study. The highest mobility enhancement was observed under white light irradiation. It was found that the photocurrent/dark-current ratio was affected by the power density of light sources. The photoresponsivity was affected by the matching of the absorbance of Cl-PEPTC microribbons and the emitting spectrum of light sources. Finally, Cl-PEPTC field-effect transistor was measured under different temperature. It was found that the mobility was enhanced with increasing temperature.

Organic thin film transistors witch had low temperature process (<100 oC) , large area manufacturing and low cost compared to FET and have revealed a great potential to substitute inorganic thin film transistors. P-type organic semiconductor technology has been rather developed than N-type organic semiconductor therefore researchers have started the study for N-type organic semiconductor. The thesis use CVD to grow ZnO nanowires and hope to add into N-type organic thin film transistors to form Composite thin film transistors in order to enhance properties. Here we use PDIF-CN2 as our N-type organic semiconductor material because it had better property (0.15 cm2/Vs)and air-stable than other N-type materials. Our study combine Zinc oxide nanowires with an N-type organic semiconductor as composite OTFTs and compare their electrical performance with pristine OTFTs. The composite OTFT’s carrier current is three to four times (1.2x10-4 A-> 4x10-4 A) higher than that of pristine OTFT and current mobility is enhanced by two to three times (0.17 cm2/Vs->0.5 cm2/Vs).

In this thesis, we demonstrate a low reflection organic light-emitting device (OLED) with the reflectance of 7.32 % which is 10 times smaller than that of the control device by using the double metal configuration as the semi-transparent metal layer, and using a perylene derivative, as an absorption and interference layer. In addition to the good display characteristics and electrical performances of this low-reflection OLED, this device also exhibits the unusual photo-sensitive characteristics. Also, we study a new acceptor material, in the application of organic solar cell (OSC). With incorporating the donor material, pentacene, the highest power conversion efficiency of the OSC incorporates is 0.05% under the AM1.5 solar illumination.

This thesis can be divided into 2 parts. The first was concentrated on designing and synthesizing donor materials for the organic photovoltaics (OPVs). The second part was focused on developing of electron transporting materials for the perovskite solar cells (PVSCs). In the first part, we have synthesized and characterized a series of diketopyrrolopyrrole (DPP)-oligothiophene copolymers, of which the number of regioregular oligothiophene ring (2T, 3T and 4T) and the arrangement of the alkyl side-chain on regioirregular quarterthiophene (4T0, 4T1 and 4T2) are variable. The side chains with regioregular lead to more planar copolymer backbones and higher short circuit current (JSC), but backbone torsion (due to regioirregular side chains) generates greater open-circuit voltages (VOC) for DPP-oligothiophene copolymers. The increasing thiophene ring progressively raises HOMO energy level of copolymers but marginally affects their band gaps. Additionally, the HOMO energy level was found declined significantly with side-chain regioirregularity, because of reducing length of π-conjugation. The HDDPP4T0 exhibits the strongest absorption, extensive network structure, and high hole mobility (µh = 6.04 × 10-4 cm2 V-1 s-1). These characteristics contribute to the exceptional high JSC of 18.96 mA cm-2 for OPV with PCE = 6.12%. However, the HDDPP4T1 having an optimal combination of π-conjugation and energy level affords the second highest VOC (0.73 V) and the third highest JSC (16.89 mA cm-2), resulting the best PCE of 7.51 % among all. X-ray scattering, transmission electron microscopy, atomic force microscopy, and space-charge-limited-current (SCLC) easurements reveal that the solvent additive of diphenylether (DPE) enables PC71BM-blended copolymers thin film in crystallinic fibril with enhanced hole mobility. In the second part, we have developed and demonstrated three solution processable perylene diimides, i.e., X-PDI, X = H, F, or Br, as nonfullerene electron accepting and electron transporting materials in inverted PVSCs. Whereas H-PDI or F-PDI performs unsatisfactorily, our best PVSC is based on Br-PDI exhibiting PCE of 3.23%, which is just a bit shy of 4.13% of fullerene (PC61BM) PVSCs. Through a series of physical, spectroscopic, and microscopic studies, we have understood that the low solubility of F-PDI is a major factor causing the poor quality of the thin film, rendering virtually no photovoltaic effect for F-PDI. Although the solubility of H-PDI is better than F-PDI, the inferior electron mobility and conductivity make H-PDI PVSCs have relatively worse performance. Having the highest solubility, electron mobility, and conductivity among X-PDI, Br-PDI based PVSCs are almost as efficient as PC61BM based PVSCs. Within the ZnO NP as a CBL in the PVSCs, the PCEs of PVSCs based on X-PDI or PC61BM are significantly improved to 7.78%, 10.50%, and 11.07%, respectively.We infer that the CBL of ZnO NP has the function of interspacelling on the defect of X-PDI or PC61BM thin film, reducing the direct contact of Ag cathode to the perovskite material. Due to the strong molecular interaction, F-PDI aggregates significantly in thin film, creating too many and too large defects to be remedied or improved with or without CBL of ZnO NP. Very poor electron mobility and conductivity of F-PDI are two other factors devastating its PVSCs. Through this study, we have demonstrated that the simple mono-bromine substituted perylene diimide (Br-PDI), is solution processable and has potential for use as a non-fullerene electron accepting and electron transporting material in inverted PVSCs.

The characteristics of pentacene/perylene derivatives based organic solar cells are discussed in this thesis. Donor and acceptor layers are pentacene and N,N'-dioctyl-3,4,9,10-perylenetetracarboxylic diimide (PTCDI-8C) or N,N′-Ditridecylperylene-3,4,9,10-tetracarboxylic diimide (PTCDI-13C) respectively. Two organic solar cells, pentacene/PTCDI-8C heterojunction and pentacene/PTCDI-13C heterojunction, were fabricated to compare the influence of power conversion efficiency among perylene derivatives with various numbers of carbon molecules. Under the sunlight simulator with AM1.5G filter and 100 mW/cm2, the solar cells of pentacene/PTCDI-13C heterojunction with Ag/Al cathode has J-V characteristics of short-circuit current density of 0.415 mA/cm2, open-circuit voltage of 0.413 V, fill factor of 0.55, and power conversion efficiency of 0.095%, which are better than those of pentacene/PTCDI-8C heterojunction. In pentacene/PTCDI-8C based solar cells, the short-circuit current density, open-circuit voltage, fill factor and power conversion efficiency are 0.4 mA/cm2, 0.378 V, 0.49, and 0.074%, respectively. Moreover, according to the thin film analysis, the PTCDI-13C thin film’s excitons in the surface of heterojunction for dissociation are more and the probability of radiative recombination of electron-hole pair is less than PTCDI-8C. The PTCDI-13C thin-film possesses better carrier mobility than PTCDI-8C. Therefore, we could conclude that those factors mentioned above are the keys of the pentacene/PTCDI-13C based solar cells with better power conversion efficiency.

In order to enhance the photovoltaic (PV) performance of perovskite solar cells (PSCs), the perylene diimide derivative (FC) and PCBM were synthesized and added into the perovskite based photoactive layer to reduce the grain boundary defect and enhance the coverage of perovskite film, and absorbance of the active layer. The FC and PCBM were respective mixed into the perovskite precursor solution with different concentrations. By adjusting the heat treatment temperature of the active layer and the added amount of toluene during the device fabrication process, good perovskite crystal films with heterojunction structure were obtained which was corresponding to the reduction of pinhole defects and enhancement of crystal size. As results, higher PV properties of the PSCs were obtained. The architexture of PSC is ITO/PEDOT:PSS/Perovskite/PCBM/Ag. An open circuit voltage of 0.88 V, a short-circuit current of 11.22 mA/cm2, a fill factor of 0.75, and the photoelectronic conversion efficiency (PCE) of 7.41%, were obtained for the PSC. The optimal doping amount of FC and PCBM was mixed into the perovskite precursor solution (MAI/PbI2, 1 mL) to prepare the photoactive layer witha heterojunction structure. The An open circuit voltage of 0.80 V, the short circuit current of 17.94 mA/cm2, the fill factor of 0.84, and the PCE of 12.06 % were obtained for the PSC doped with FC. The efficiency of 10.37%, open circuit voltage of 0.85 V, short-circuit current of 15.25 mA/cm2, and fill factor of 0.80 were obtained for the PSCs doped with PCBM. Through the proper addition of FC or PCBM, the absorbance of active layer can be increased, and the defects of perovskite crystals can be compensated, and both of the hydrophobicity of the active layer and theelectron-transfer ability from active layer to electron transport layer were enhanced. PV performance of PSCs were therefore improved by the addition of FC and PCBM.

In this thesis, we used Electroabsorption Spectroscopy(ER), I-V Curve and Photoluminscence(PL) to investigate the electro-optical properties of Perylene Diimide Derivative-PTCDI with various Alkyl (PTCDI-CxH2x+1, x = 2,3,4,5,6,7,8). We can understand the internal electric field distribution by I-V Curve measurement. Without illumination, the electric field is Schottky diode like distribution in the organic layer; nevertheless, with the lighting, it is Space charge limited electric field distribution. Between the range of the applied voltage(+1.4 ~ -1.4 Vac), the I-V Curve is linear behavior. In ER measurements, a AC voltage as external electric field is applied to the sample, and it will cause the Stark effect. The structures of the spectrum are formed with the first and second order differential of Gauss functions. Compare with absorption measurement and the reference, the structure in 2.2 eV should be the HOMO-LUMO transition. Further, the strength of ER is direct proportion to the applied AC voltage. In PL measurement, the transitions all below the HOMO-LUMO transition. The relation between the strength of PL and temperature can explain by the thermal activated non-radiative recombination model.

We have studied the thin-film transistors and electronic transport properties of n-type organic semiconductor, N,N'-dioctyl-3,4,9,10- perylene tetracarboxylic diimide(PTCDI-8C). Inverted staggered transistor structure with a bottom gate was used to form the PTCDI-8C-based thin- film transistors in which the thin films of the PTCDI-8C were prepared by thermal evaporation. Two research topics are contained in the thesis. In the first topic, we investigated the relationship between PTCDI-8C thin-film transistors characteristics and surface energy of polyimide (PI) played a role as a modification layer on gate dielectric surface. In the second topic, a series of the thin-film transistors were fabricated under different annealing temperatures. The mobility of organic thin-film transistors has been improved from 0.07 to 0.6 cm2/Vs by using PI as a modification layer due to reducing of the surface free energy of SiO2 dielectric. After thermal treatments under 50 – 110 °C, the high electron mobility of 0.8 cm2/Vs was achieved at 70 °C. At the same time, the smallest half-width of X-ray diffraction peak under annealing temperature of 70 °C indicates that a more homogeneous microstructure associated with lower molecular relaxation energy could benefit carrier transportation.
