Abstract:
In this study two pairs of novel zinc-porphyrin complexes (ZnP1 ZnP2 ZnP3 and ZnP4) were synthesized as sensitizers for DSSC and their photophysical, computational studies and photovoltaic properties were investigated. Structures of proposed dyes are based on a molecular design that relies on donor/[Formula: see text]-bridge/acceptor interactions. Compounds differ by anchoring mode to the titanium dioxide surface: ZnP2 and ZnP4 porphyrins possess carboxyl anchoring groups while ZnP1 and ZnP3 porphyrins have similar structure but without anchors and attached to the surface by isonicotinic acid ligands. All the zinc-porphyrin derivatives bear hexyloxy-chains at the para-positions of their phenyl rings and ZnP3 and ZnP4 contain 1,3,5-triazine fragments as efficient electron transfer bridges. Electron density distribution of the frontier molecular orbitals was calculated based on the density functional theory (DFT). The test DSSC was manufactured and its parameters were measured to compare the effectiveness of the proposed sensitizers. Our results reveal that dyes with an anchoring group directly in their structure demonstrated several times higher efficiency. The use of the triazine fragment proved effective for the introduction of acceptor substituents bearing anchor groups. As a result, the highest efficiency of 4.33% was achieved using the dye ZnP4.

Abstract:
Two zinc porphyrins substituted at the meso-positions with different donor units (denoted as ZnP1 and ZnP2) have been designed and synthesized to construct new self-assemblies (denoted as ZnPx-ZnPA) with anchor porphyrin (ZnPA) dyads formed by the coordination bonds of Zn-to-ligand approach. Then these assemblies were absorbed on the semiconducting TiO2 electrode surfaces by the carboxylic groups of anchor porphyrin (ZnPA) to build dye sensitized solar cells. Their spectral properties, electrochemical, theoretical calculations and photovoltaic properties were systematically investigated. Interestingly, these self-assemblies devices compared to monomer anchoring porphyrin device showed higher [Formula: see text] and [Formula: see text]. Especially, the dyad of ester-based zinc porphyrin (ZnP2) assembly device has the highest photoelectric conversion efficiency. The assembled modes of the assemblies immobilized on TiO2 electrode surfaces were also verified by transmission electron microscopy (TEM).

Abstract:
L'érythroblaste, qui dispose d'une quantité de fer normale, synthétise de l'hémoglobine en plusieurs étapes, dont la dernière est l'incorporation de Fe++ dans la protoporphyrine sous l'action de la ferrochélatase mitochondriale. Lorsque pour une raison ou une autre, l'érythroblaste manque d'ions Fe++, la ferrochélatase va incorporer du Zn++ à la place et synthétiser ainsi la ZnPP. Son augmentation signale donc une déficience de Fe++ au niveau des mitochondries des érythroblastes. Après avoir étudié la ZnPP dans un certain nombre de pathologies connues pour avoir des répercutions sur le métabolisme du fer et l'érythropoïèse, nous arrivons à la conclusion que la ZnPP n'est pas destinée à remplacer un paramètre du bilan hématologique martial, mais constitue une information supplémentaie précieuse dans l'exploration de tous les désordres du métabolisme du fer

Uma das alternativas mais promissoras para o tratamento do câncer é a Terapia Fotodinâmica (TFD). A Ftalocianina de Zinco (ZnPc) é um fotossensibilizante de segunda geração com caráter hidrofóbico e necessita ser incorporado em um sistema de liberação adequado para ser injetado sistemicamente. Nanopartículas magnéticas, NPMs, constituída principalmente de magnetita (Fe3O4) apresentam alto valor de magnetização com grande potencial de aplicação no tratamento do câncer por hipertermia. O encapsulamento simultâneo de fármacos com NPMs tem sido reconhecido como uma técnica promissora para o tratamento do câncer por possibilitar a ação sinergética dos diferentes tipos de tratamento. O objetivo deste trabalho foi a síntese, caracterização e avaliação da toxicidade e fototoxicidade das NPMs, do encapsulamento da NPMs e ZnPc e o encapsulamento simultâneo de ZnPc com NPMs via polimerização em miniemulsão. As NPMs com ácido oléico (AO) foram preparadas pelo método de co-precipitação em meio aquoso e a análise de DRX mostrou picos característicos da magnetita (Fe3O4) com diâmetro médio de nanopartículas de 13nm. As NPMs apresentaram um alto valor de magnetização de saturação (Ms) (64 emu/g óxido de ferro). O encapsulamento das NPMs foi realizado via polimerização em miniemulsão com metacrilato de metila (MMA). As NPMs encapsuladas apresentaram um diâmetro aproximado de 100nm com valor de Ms de 34 emu/g de óxido de ferro. Para o encapsulamento da ZnPc utilizou-se duas técnicas de encapsulamento. A primeira foi a técnica de miniemulsão com auxílio da técnica de nanoprecipitação (PMMA/ZnPc)(FA)) e a segunda utilizou-se apenas a técnica de miniemulsão direta (PMMA/ZnPc(FO)). O teor de ZnPc nas nanopartículas poliméricas foi um pouco superior na amostra PMMA/ZnPc(FA) (3,7µg/mg) do que na amostra de PMMA/ZnPc(FO) (3,0 µg/mg). Ambas as técnicas resultaram em um tamanho médio de aproximadamente 100nm. Ao encapsular a ZnPc simultaneamente com as NPMs (PMMA/ZnPc/NPMs) não alteração em relação ao tamanho das nanopartículas (100nm), concentração de ZnPc (3,6 µg/mg) e propriedades magnéticas (31 emu/g de óxido de ferro) em relação ao encapsulamento em separado da ZnPc e NPMs. A liberação da ZnPc das nanopartículas poliméricas foi sustentada e lenta. Nas primeiras 20 horas cerca de 5-10% do ZnPc contida nas nanopartículas poliméricas foi liberada em todas as amostras. No ensaio de toxicidade (ausência de luz), as nanopartículas encapsuladas mostraram baixa toxicidade. No ensaio de atividade fotobiológica, observou-se, que a luz isoladamente (sem nanopartículas contendo ZnPc) não foi capaz de induzir efeito citotóxico sobre a cultura de células. Ao utilizar nanopartículas contendo ZnPc observou-se uma redução acentuada da viabilidade celular para 22% (PMMA/ZnPc(FA)) e 30% (PMMA/ZnPc/NPMs).

Abstract : Photodynamic therapy (TFD) is one of the most promising alternatives for the treatment of the cancer. Zinc phtalocyanine (ZnPc) is a second generation photosensitizer with hydrophobic character that should be incorporated in a suitable delivery system to be injected systemically. Magnetics nanoparticles (NPMs) consisting mainly of magnetite (Fe3O4) present high value of magnetization with great potential of application in the treatment of the cancer by hyperthermia. The simultaneous encapsulation of drugs with NPMs has been recognized as one promising technique for the treatment of the cancer making possible a synergetic action of the different types of treatment. The objective of this work was the synthesis, characterization and evaluation of the toxicity and phototoxicity of the NPMs, the encapsulation of the NPMs and ZnPc and the simultaneous encapsulation of ZnPc with NPMs by miniemulsion polymerization. The NPMs with oleic acid (AO) had been prepared by the co-precipitation method in aqueous solution. DRX analysis showed characteristic peaks of magnetite (Fe3O4) with average particle diameter of 13nm. The NPMs had presented high value of magnetization of saturation (Ms) (61 emu/g of iron oxide). The encapsulation of the NPMs was carried through methyl methacrylate (MMA) miniemulsion polymerization. The polymeric particles with NPMs encapsulated presented an average diameter of 100nm with value of Ms of 34 emu/g of iron oxide. Two techniques of encapsulation were employed for the encapsulation of ZnPc. The first one was the miniemulsion polymerization with the nanoprecipitation technique (PMMA/ZnPc) (FAN)) and second one used only the miniemulsion polymerization technique (PMMA/ZnPc (FO)). The amount of ZnPc in polymeric nanoparticles was higher in PMMA/ZnPc(FA) sample (3,7µg/mg) when compared to the sample of PMMA/ZnPc (FO) (3,0 µg/mg). Both techniques resulted in polymeric nanoparticles with an average diameter of approximately 100nm. The simultaneous encapsulation of ZnPc with NPMs (PMMA/ZnPc/NPMs) presented very similar values of average particle size (100nm), concentration of ZnPc (3,6 µg/mg) and magnetic properties (31 emu/g of iron oxide) when compared to the single encapsulation of ZnPc and NPMs. The release of the encapsulated ZnPc was supported and slow. In the first 20 hours approximately 5-10% of the encapsulated ZnPc was released in all samples. In the toxicity assay (light absence), the encapsulated nanoparticles had shown low toxicity. In the assay of phototoxicity activity, it was observed that the light (without polymeric nanoparticles containing ZnPc) was not able to induce cytotoxic effect on the culture of cells. When using polymeric nanoparticles with encapsulated ZnPc an accentuated reduction of the cellular viability of 22% (PMMA/ZnPc (FA)) and 30% (PMMA/ZnPc/NPMs) was observed.

Abstract:
The field of hybrid electronics of molecules and traditional semiconductors is deemed to be a realistic route towards possible use of molecular electronics. Such hybrid electronics finds its potential technological applications in nuclear detectors, near-infrared detectors, organic thin film transistors and gas sensors. Specifically Metal / organic / n-Silicon structures in this regard are mostly reported to have two regimes of charge transport at lower and higher applied voltages in such two terminal devices. The fact is mostly attributed to the change in conduction mechanism while moving from lower to higher applied voltages. These reports describe interactions between the semiconductors and molecules in terms of both transport and electrostatics but finding the exact potential distribution between the two components still require numerical calculations. The challenge in this regard is to give the exact relations and the transport models, towards practical quantification of charge transport properties of metal / organic / inorganic semiconductor devices. Some of the most exiting questions in this regard are; whether the existing models are sufficient to describe the device performances of the hybrid devices or some new models are needed? What type of charge carriers are responsible for conduction at lower and higher applied voltages? What is the source of such charge carriers in the sandwiched organic layer between the metal and inorganic semiconductors? How the transition applied voltage for the change in conduction mechanism is determined? What is the role of dopants in the organic layer semiconductors? What are the possible explanations for observed temperature effects in such devices? In present work the charge transport properties of metal / metal-phthalocyanine / n-Si structures with low (ND = 4×1014 cm-3), medium (ND = 1×1016 cm-3) and high (ND = 2×1019 cm-3) doped n-Si as injecting electrode and the effect of air exposure of the vacuum evaporated metal-phthalocyanine film in these structures is investigated. The results obtained through temperature dependent electrical characterizations of the structures suggest that in terms of dominant conduction mechanism in these devices Schottky-type conduction mechanism dominates the charge transport in low-bias region of these devices up to 0.8 V, 0.302 V and 0.15 V in case of low, medium and high doped n-Silicon devices. For higher voltages, in each case of devices, the space-charge-limited conduction, controlled by exponential trap distribution, is found to dominate the charge transport properties of the devices. The interface density of states at the CuPc / n-Si interface of the devices are found to be lower in case of lower work function difference at the CuPc / n-Si interface of the devices. The results also suggest that the work function difference at the CuPc / n-Si interface of these devices causes charge transfer at the interface and these phenomena results in formation of interface dipole. The width of the Schottky depletion region at the CuPc / n-Si interface of these devices is found to be higher with higher work function difference at the interface. The investigation of charge transport properties of Al / ZnPc / medium n-Si and Au / ZnPc / medium n-Si devices suggest that the Schottky depletion region formed at the ZnPc / n-Si interface of these devices determines the charge transport in the low-bias region of both the devices. Therefore, the Schottky-type (injection limited) and the space-charge-limited (bulk limited) conduction are observed in the low and the high bias regions of these devices, respectively. The determined width of the Schottky depletion region at the ZnPc / n-Si interface of these devices is found to be similar for both the devices, therefore, the higher work function difference at the metal / ZnPc interface of the devices has no influence on the Schottky depletion region formed at the ZnPc / n-Si interface of the devices. The similar diode ideality factor, barrier height and the width of the Schottky depletion region, determined for both of these devices, demonstrates that these device characteristics originate from ZnPc / n-Si interface of these devices. Therefore, the work function difference at the metal / ZnPc interface of these devices has no noticeable influence on the device properties originating from ZnPc / n-Si interface in these devices. The investigation of charge transport properties of Al / CuPc / low n-Si devices with and without air exposure of the CuPc film, before depositing metal contact demonstrate that Schottky-type conduction mechanism dominates the charge transport in these devices up to bias of 0.45 V in case devices with the air exposure, and up to 0.8 V in case devices without the air exposure. This decrease in the threshold voltage, for the change in conduction mechanism in the devices, is attributed to wider Schottky depletion width determined at the CuPc / n-Si interface of the devices without the air exposure of CuPc film. For higher voltage the space-charge-limited conduction controlled by exponential trap distribution, is found to dominate the charge transport properties of the devices without the air exposure of CuPc, and in case of devices with the air exposure of CuPc film, the SCLC is controlled by single dominating trap level probably introduced by oxygen impurities.

Abstract:
Detonations in gases usually propagate with lateral strain rates, in either weakly confined or varying-cross-section or curved or even small-sized geometries. Lateral strain rates have been generally known to significantly impact the detonation dynamics, i.e., decreasing the propagation speeds lower than the theoretical Chapman-Jouguet (CJ) velocities, increasing the propagation limit pressures as well as cell sizes. Since the detonation-based engines require the reliable control of the accurate ignition and stable propagation of a detonation wave, it is desirable to have the predictive capability of the response of detonation dynamics to lateral strain rates, for achieving the practical purposes of detonation applications. Therefore, the present thesis aims to provide such predictability, by quantifying the effect of lateral strain rates on detonation dynamics from both the experimental and numerical modelling perspectives. Experimentally, this study extended the exponential horn technique of Radulescu and Borzou (2018) to a range of characteristic mixtures with varied detonation instability levels, i.e., from the weakly unstable system of 2H₂/O₂/7Ar to the highly unstable one of CH₄/2O₂. Steady detonation waves were obtained at the macro-scale, with the very regular H₂/O₂/Ar detonation cellular structures characterized by reactive transverse waves while the unstable hydrocarbon-oxygen detonation reaction zone structures in the presence of significant unreacted gas pockets. The meaningful D-K curves characterizing the relationships between the detonation mean propagation speeds and lateral strain rates were directly obtained from experiments. Comprehensive comparisons were then made between experiments and predictions from the generalized ZND model with lateral strain rates. Excellent agreement was found for the stable H₂/O₂/Ar detonations due to the much longer thermally insensitive reaction zone lengths compared to the characteristic induction zone lengths, while substantial departures exist for the highly unstable CH₄/2O₂ detonations. The degree of departure was found to correlate well with the detonation instability. As compared to the laminar ZND wave, the more unstable hydrocarbon-oxygen detonations manifested themselves in the significantly enhanced global rates of energy release with the notably suppressed thermal character of ignition. Implications of such a globally enhanced burning mechanism highlight the important role of diffusive processes involved in turbulent burning of the unreacted gas pockets. Finally, empirical global reaction rate laws were developed for effectively capturing the dynamics of unstable detonations. Numerically, this work proposed a novel model for evaluating the effect of boundary layer losses on cellular structures of 2D detonations in narrow channels. The boundary-layer-induced lateral strain rate was evaluated using the negative boundary layer displacement of Mirels' theory. With the theoretical Mirels' constant KM reduced by a factor of 2, the experimentally obtained 2H₂/O₂/7Ar detonations can be very well reproduced by simulations using the resulting quasi-2D formulation. It was further found out that detonation cellular cycle dynamics can be modified by the presence of boundary layer losses, yielding larger velocity fluctuations and more rapid decay rates of the lead shock. The exponential sensitivity of detonation cell sizes to velocity deficits, controlled by the global activation energy, highlights the importance of providing the detonation speed when reporting experimentally measured cell sizes.

Abstract:
This work deals with the investigation and research on organic solar cells. In the first part of this work we focus on the spectroscopical and electrical characterization of the acceptor molecule and fullerene derivative C70. In combination with the donor molecule zinc-phthalocyanines (ZnPc) we investigate C70 in flat and bulk heterojunction solar cells and compare the results with C60 as acceptor. The stronger and spectral broader thin film absorption of C70 and thus enhanced contribution to photocurrent as well as the similar electrical properties with respect to C60 result in higher power conversion efficiencies. In the second part, modifications of the blend layer morphology of a C60:ZnPc bulk heterojunction solar cell are considered. Using substrate heating during co-deposition of acceptor and donor, the molecular arrangement is influenced. Due to the additional thermal energy at the substrate the blend layer morphology is improved and optimized for a substrate heating temperature of 110°C. With transmission electron microscopy, molecular phase separation of C60 and ZnPc and the formation of polycrystalline ZnPc domains in a lateral dimension on the order of 50 nm are detected. Mobility measurements show an increased ZnPc hole mobility in the heated blend layer. The improved charge carrier percolation and transport are confirmed by the enhanced performance of such bulk heterojunction solar cells. Furthermore, we show a strong influence of the pre-deposited p-doped hole transport layer on the molecular phase separation. In the third part, we study the dependency of the open circuit voltage on the mixing ratio of C60 and ZnPc in bulk heterojunction solar cells. For the different mixing ratios we determine the ionization potentials of C60 and ZnPc. Over the various C60:ZnPc blends from 1:3 - 6:1, the ionization potentials change linearly, but different from each other and exhibit a correlation to the change in open circuit voltage. Depending on the mixing ratio an intrinsic ZnPc layer adjacent to the blend leads to injection barriers which result in reduced open circuit voltage. We hence determine a voltage loss dependent on ZnPc layer thickness and barrier height
Diese Arbeit beschäftigt sich mit der Untersuchung und Forschung an organischen Solarzellen und gliedert sich in drei Teile. Im ersten Teil wird auf die spektroskopische und elektrische Charakerisierung des Fullerenderivates C70 eingegangen, welches als Akzeptormolekül in Kombination mit dem Donormolekül Zink-Phthalocyanin (ZnPc) in Flach- und Mischschichtheteroübergänge organischer Solarzellen Anwendung findet. Dabei wird das Molekül mit dem bisherigen Standard Akzeptormolekül C60 verglichen. Die deutlich stärkere und spektral verbreiterte Dünnschichtabsorption von C70, sowie die vergleichbaren elektrischen Eigenschaften zu C60 führen zu einer Effizienzsteigerung in den Flach- und Mischschichtsolarzellen, welche maßgeblich durch die Erhöhung des Kurzschlussstromes erreicht wird. Im zweiten Teil widmet sich diese Arbeit der Morphologiemodifizierung des Mischschichtsystems C60:ZnPc, welche durch Heizen des Substrates während der Mischverdampfung von Akzeptor- und Donormolekülen in organischen Mischschichtsolarzellen erreicht werden kann. Es wird gezeigt, dass mit der zusätzlichen Zufuhr thermischer Energie über das Substrat die Anordnung der Moleküle in der Mischschicht beeinflusst werden kann. Unter Verwendung eines Transmissionselektronmikroskops lässt sich für die Mischschicht mit der optimalen Solarzellensubstrattemperatur von 110°C eine Phasenseparation von C60 und ZnPc unter Ausbildung von polykristallinen ZnPc Domänen in der lateralen Dimension von 50 nm nachweisen. Mit zusätzlichen Messungen der Ladungsträgerbeweglichkeiten des Mischschichtsystems kann die verbesserte Perkolation und Löcherbeweglichkeit von ZnPc für die Steigerung der Performance geheizter Solarzellen bestätigt werden. Desweiteren wird gezeigt, dass die Ausbildung einer Phasenseparation sehr stark von der darunter liegenden Molekülschicht z.B. der p-dotierte Löchertransportschicht abhängig ist. Im letzten und dritten Teil geht die Arbeit auf die Abhängigkeit der Klemmspannung von der Mischschichtkonzentration von C60 und ZnPc ein. Für die unterschiedlichen Volumenkonzentrationen von C60:ZnPc zwishen 6:1 und 1:6 kann gezeigt werden, dass sich die Ionisationspotentiale von C60 und ZnPc über einen großen Bereich linear und voneinander verschieden verändern und mit den absoluten Änderung der offenenen Klemmspannung korrelieren. Desweiteren wird gezeigt, dass sich durch eine zusätzlich an die Mischschicht angrenzende intrinsische ZnPc Schicht, abhängig von der Mischschichtkonzentration, Injektionsbarrieren ausbilden, welche nachweislich einen Spannungsverlust bedingen. Dabei kann gezeigt werden, dass der Spannungsverlust mit der ZnPc Schichtdicke und der Barrierenhöhe korreliert

Single organic layers of zinc-phthalocyanine (ZnPc), fullerene C60 and bathocuproine (BCP) were deposited inside this chamber and characterized ex situ by spectroscopic ellipsometry. The preparation of an organic photovoltaic (OPV) cell based on the before characterized single layers, demonstrates that it is possible to deposit complex layer structures and characterize them electrical in situ
