Abstract:
Certainly, the success of polythiophenes is due in the first place to their outstanding electronic properties and superior processability. Nevertheless, there are additional reasons that contribute to arouse the scientific interest around these materials. Among these, the large variety of chemical modifications that is possible to perform on the thiophene ring is a precious aspect. In particular, a turning point was marked by the diffusion of synthetic strategies for the preparation of terthiophenes: the vast richness of approaches today available for the easy customization of these structures allows the finetuning of their chemical, physical, and optical properties. Therefore, terthiophene derivatives have become an extremely versatile class of compounds both for direct application or for the preparation of electronic functional polymers. Moreover, their biocompatibility and ease of functionalization make them appealing for biology and medical research, as it testifies to the blossoming of studies in these fields in which they are involved. It is thus with the willingness to guide the reader through all the possibilities offered by these structures that this review elucidates the synthetic methods and describes the full chemical variety of terthiophenes and their derivatives. In the final part, an in-depth presentation of their numerous bioapplications intends to provide a complete picture of the state of the art.

Abstract:
Thesis presents synthesis and study of thiophene monomers, oligomers and polymers. The new series of thieno[3,4-b]pyrazine copolymers based on 3-dodecylthiophene and pyrazine monomers were prepared by oxidative polymerization with FeCl3. The effective synthetic method for preparation of 3-alkylthiophenes and thiophene oligomers was developed by optimizing of Kumada cross-couplig. The mentioned method could be realized for multikilos scale with possibility of transfer to pilot plant production. The second part of thesis focuses on synthesis and study of new thiophene compounds, which consist of both 2,3-diazo-1,3-butadiene bridge with two terminal chromophores and two thiophene units linked together via -position by pyrazine or hydrazine bridge. Finally, the new type of regular alternating copolymer consists of 2,2´:5´,2´´-terthiophene-5,5´-dicarboxylic acid (TEDA) and polyethyleneoxide (PEO) was prepared. Formation of polymer nano-subunits as separated phases in solid state was confirmed by TEM.

Abstract:
As a means of reducing the dependence on fossil fuels, generation of hydrogen (H₂) has been proposed as a route for storing energy in a chemical bond. To access this energy, H₂ can be combusted with oxygen or used in a fuel to release the energy stored in the chemical bond, while generating water as the byproduct. To generate the hydrogen necessary to fuel a hydrogen economy, an energy efficient and stable catalyst needs to be designed. The work presented in this thesis describes the investigation of a catalytic mimic inspired by the [FeFe]-hydrogenase enzyme. The design of this and similar mimics have been pursued as the active site of the enzyme is composed of readily available and abundant elements, and has a turnover rate of 6000-9000 molecules of H₂ s⁻¹. The catalyst in this work was studied via cyclic voltammetry and density functional theory calculations to determine the catalytic activity as well as a mechanism for H₂ production of the complex. The complex 2,5-bis-(2',2"-thiophen-2-yl)-thiophene-µ-3,4-dithiolato)diiron hexacarbonyl, 1, was prepared and found to catalyze the production of molecular hydrogen in CH₂Cl₂, however the overpotential for catalysis was not determined as the standard potential of acetic acid in CH₂Cl₂ is not known. Comparison of the catalytic potentials of terthiophene-cat to µ-(1,2-benzenedithiolato)diiron hexacarbonyl, 2, and µ-(3,4-thiophenedithiolato)diiron hexacarbonyl, 3, in CH₂Cl₂ showed that 1 had a less negative potential (0.14 V and 0.16 V, respectively) for the catalytic reduction of protons to H₂. Electrochemical investigations combined with density functional theory (DFT) indicated that 1 has an ECEC mechanism for the reduction of protons, where E is an electrochemical step and C is a chemical process. The proposed mechanism for 1 is similar to that of 2 and 3, with 1 catalyzing the production of H₂ using acetic acid at a less negative potential than 2 and 3.

Abstract:
The discovery of conducting and semiconducting polymers has opened the possibility to produce integrated circuits entirely of plastic with standard continuous printing techniques. Nowadays several of this polymers are commercial available, however the performances of this materials are strongly affected by their supramolecular order achieved after deposition. In this research, the influence of some standard printing techniques on the electrical performances of conjugated polymers is evidenced in order to realise logic devices with these materials.

In this study, a series of new two-dimensional conjugated polymers with benzodithiophene (BDT) unit, including PTBDT、P3TBDT、P3TBDTDT and P3TBDTCN were designed and synthesized using Stille coupling polymerization methed. These polymers bear terthiophene groups as conjugated side-chains and vinyl groups as conjugated bridge to link the side-chains to polymer backbone. To enhance the solubility, each terminal thiophenes of the terthiophene unit was incorporated with one ethylhexyl group. To reduce the crowd of effect in PTBDT, two thiophene rings were inserted into the backbone as space to form P3TBDT；moreover, the two ends of terthiophene side group in P3TBDT were further chemically modified with two different acceptor units, 1,3-diethyl-2-thiobarbituric and ethyl-2-cyanoacetate, to yield P3TBDTDT and P3TBDTCN, respectively. All intermediates and monomers were characterized using 1H NMR, 13C NMR, COSY, HSQC, HMBC and HRESI mass spectrometry. The properties of as-synthesized copolymers were characterized by UV-vis absorption spectrometer, X-ray Diffractometer, photoelectron spectrometer AC-2 and cyclic voltammetry. Gel permeation chromatography (GPC) was employed to determine the molecular weight characteristics of the final polymers. Experimental results show that inserting two thiophenes as spacer into the main chain of P3TBDT improves the coplanarity and increases the effective conjugation length of the polymer backbone. Compared with PTBDT, P3TBDT exhibits a narrower bandgap, a broader absorption spectrum and an enhanced absorption coefficient. Moreover, the incorporation of electron-withdrawing units to the terthiophene side groups in P3TBDTDT and P3TBDTCN greatly red-shifts the absorption of terthiophene into visible range and overlap with the absorption of main-chain that substantially increases the light-harvesting capability of polymer in a specific wavelength region.

In others' research showed that bithiophene and terthiophene rivatives have the great potentoal to be developed into therapeutic agents against infectious diseases or cancers. Some of them have the phototoxicity under UV light or sunlight. In the dark, one can increase the quantity and get the same effect. we want to use them as therapeutic agents, we have to increase their solubility in water or hydrophilic solvent and decrease the toxicity. Thus, our laboratory synthesize a series of new hydro- philic bithiophene and terthiophene derivatives, including: 5-(2- iminoethanol)-2,2'-bithiophene(5), 5-(2-methylaminoethanol)-2,2'- bithiophene(6), 5-(2-iminoethanol)-2,2':5',2"-terthiophene(7),(2- methylaminoethanol)-2,2':5',2"-terthiophene(8), 1,2-bis( 2,2'-bithiophene-5-imino)ethylene(9), 5-(2-methylaminoethylamine) -2,2'-bithiophene(10), 1,2-bis(2,2':5'2"-terthiophene-5-imino) ethylene(11), 5-(2-(2-imino)ethylaminoethanol)-2,2'-bithiophene( 12) and 5-(2-(2-imino)ethylaminoethanol)-2,2':5'2"-terthiophene( 13) for supplying advanced biological activity test.

In this study, a series of new two-dimensional polythiophene derivatives with terthiophene as pendant group, including p(2EHT-BT), p(2EHT-TT), p(2EHT-DTT) and p(3EHT-DTT), were designed and synthesized. To enhance the solubility, the two terminal thiophene rings of the terthiophene unit were incorporated with ethylhexyl groups. Moreover, the bithiophene (BT) and fused thiophene families, thieno[3,2-b]thiophene (TT) and dithieno[3,2-b:2 '', 3 ''-a]thiophene (DTT), were applied as comonomer to vary the distance between two bulky terthiophene-bearing monomer and increase the extent of coplanarity of the polymer main chain. All intermediates, monomers and polymer products were characterized with 1H NMR, 13C NMR and EI mass spectrometry. Gel permeation chromatography (GPC) was employed to determine the molecular weight characteristics of the final polymers. As indicated by the XRD diffraction patterns, the insertion of BT and DTT as a spacer between two bulky monomer substantially increases the crystallinity of polymer chains. Also, the fused structure of the comonomer further enhances the crystallinity of the polymer. Additionally, both p(2EHT-DTT) and p(3EHT-DTT) exhibit more red-shifted absorption maxima and wider absorption spectra (350~660 nm) than those of p(2EHT-BT) and p(2EHT-TT), indicating the formers have longer conjugation length and better main-chain planarity compared with the latters. Importantly, CV measurements demonstrate that the HOMO level of these two two-dimensional polymers is apparently lower than that of P3HT, suggesting an improved environmental stability and an potential acceptor material for developing high-open-circuit voltage polymer solar cells.

Two series of light emitting single polymers (PFS series and PFTS series) are prepared by incorporating different contents of monomers into the main chain of polyfluorene. PFS series contain different contents of 2,2':5',2'-terthiophene moieties; PFTS series comprise 5 mol% 2,3,4,5-tetraphenyl thiophene (TP) and different amount of 2,2':5',2' -terthiophene moieties. The monomers and polymers have been characterized by mass, elemental analysis, 1H-NMR, 13C-NMR, UV/vis, GPC, thermogravimetric analysis, and fluorescence spectroscopy. The thermal properties of polymer were investigated by TGA. The decomposition temperatures (Td) of PFS series and PFTS series range from 319 to 402°C and 404 to 422°C, respectively. All differential scanning calorimetry (DSC) scans for the two series of polymers do not show any glass transition in the temperature range up to 300 °C. The optical properties of these polymers are studied by UV/vis and PL spectroscopic methods. The polymers of PFS series and PFTS series exhibit the maximum absorption in the range of 373~382 nm and 374~381nm in liquid solution, respectively. The range of 367~378 nm and 376~379 nm in thin film demonstrate the maximum absorption for both, respectively. The polymers of PFS series and PFTS series exhibit the maximum emission in the range of 411~414 nm and 413~415 nm in liquid solution, respectively. The range of 503~592 nm and 502~543 nm in thin film demonstrate the maximum absorption for both, respectively. Single layer devices (ITO/PEDOT:PSS/polymer/LiF/Al) are fabricated with these polymers. The color coordinates (0.32, 0.35) of PFTS-3 devices in the best condition for the turn-on voltage of 4.5V and the highest brightness of 558 cd/m2 could meet pure white light (0.33, 0.33) of the ideal CIE chromaticity coordinates. We can find the feed ratio of the white light emitting single polymers is 92 mol% fluorine moieties, 5 mol% TP moieties and 3 mol% 2,2':5',2'-terthiophene moieties. According to cyclic voltametry (CV), HOMO level of PFS series and PFTS series could reveal in the range of -5.61~ -5.73 eV and -5.69~ -5.73 eV, respectively. The range of -2.69~ -2.79 eV and -2.74~ -2.76 eV could indicate LUMO level of them, respectively.

The power conversion efficiency（PCE）of perovskite solar cells（PSCs）has shown a significant enhancement from 3.8 % in 2009 to 23.7 % in 2018. To increase the PCE, developing a hole-transporting material（HTM）which has superior ability of positive charge extraction and transportation is one of the important factors. In this article, three terthiophene-based hole-transporting materials named WZ40, WZ102, WZ103 have been synthesized. The compounds of WZ series exhibit amorphous property and appropriate thermal stability. However, the perovskite solar cell employing WZ102 generates a power conversion efficiency of 11.91 %, which is higher than the power conversion efficiency of 10.23 % based on PEDOT:PSS. The better performance gives it potential as a promising HTM for the further advance of PSCs.
