Resumen
Using the “crystal sponge” approach, weak organic electron donor molecules were impregnated and evenly distributed in a crystal of a metal–organic framework (MOF), with the self-assembly of the donor–acceptor pairs with electron acceptor ligands. The nanopores of the MOF confined them and induced a charge transfer phenomenon, which would not occur between donor and acceptor molecules in a bulk scale.

Resumen
Abstract Human complement protein C8 was labeled with the fluorescent chromophores fluorescein-5-isothiocyanate (FITC), 3-(4-isothiocyanatophenyl)-7-diethylamine-4-methyl coumarin (IPM), eosin-5-isothiocyanate (EOS), or Texas Red (sulforhodamine-101-sulfonyl chloride; TR) with only minor reduction in the specific hemolytic activity of the protein. The distribution of C5b-8 complexes bound to sheep erythrocyte membranes was investigated by monitoring fluorescence resonance energy transfer (RET) between the following RET donor/acceptor pairs of labeled C8: FITC-C8/EOS-C8, IPM-C8/EOS-C8, and FITC-C8/TR-C8. On binding to membranes containing pre-formed C5b67 complexes, specific RET was detected for each of the donor/acceptor pairs of labeled C8 investigated. In contrast, no energy transfer was observed for these RET donor/acceptor pairs of labeled C8 incubated in the presence of control membranes or in membrane-free solution. On the basis of a consideration of the transfer efficiency that would be expected for donor/acceptor pairs of labeled C8 that were uniformly dispersed on the membrane surface, these results suggest that C5b-8 complexes are aggregated into polymeric clusters when membrane-bound. The efficiency of donor-C8 to acceptor-C8 RET--and the hemolytic activity of membrane-bound C5b-8 (in the absence of C9)--are both related to the surface density of membrane-bound C5b67, suggesting that the physical clustering of the membrane-inserted C5b-8 complex may be related to the expression of its cytolytic activity.

Resumen
The effects of substituents and solvents on the molecular structures, excitation energies and emission energies of a series of donor-acceptor substituted spiropyrans were investigated using the density functional methods. Different donor-acceptor pairs lead to alternations of the molecular structures. A relationship between the strengths of donor-acceptor pairs and the structural parameter BLA (bond length alternation) was examined and discussed. The impact on geometrical parameters induced by the solvents is more significant than that caused by the substituents, as indicated by the larger BLA changes. The substituent and solvent effects on the UV absorption and emission spectra of open-form spiropyrans were studied by the TD-DFT method. The absorption maxima of open-form spiropyrans are expected to red shift, and the emission are expected to blue shift as the strengths of donor-acceptor pairs and the polarities of solvents increase. A simple model was adopted to mimic the substituent and solvent effects, in the framework of AM1, employing Sparkles to create an external electric field on the open-form spiropyran, in order to induce a systematical polarization of the molecular equilibrium geometry and the electronic configuration.

Resumen
This review presents the synthetic aspects and photophysical properties of trimeric systems constructed with a first unit consisting of a cofacial porphyrin and then of another porphyrin attached as a side arm. Two scenarios are dealt with. The first one is the case where the three chromophores are different, called donor 1–donor 2–acceptor, specifically where the cofacial fragment is composed of donor 1 and donor 2, and the side arm is the acceptor. They are considered as models for the apo-proteins used in the LH II (light harvesting device) in the purple photosynthetic bacteria. The second one is the case where the chromophores of the cofacial bisporphyrin residue are identical and are closely placed to each other for inter-ring π-interactions. The side arm is simply a mono-porphyrin, and therefore it is different. The cofacial bisporphyrin unit exhibits then similar characteristics to the special pairs located within the reaction center protein, and are designated as artificial special pairs. On the synthetic standpoint, the various pathways to access such models are presented fully exploiting the Suzuki methodology. On the photophysical side, a large emphasis will be placed on the singlet energy transfers. Cascade processes in the trimers donor 1–donor 2–acceptor are presented and each individual contributions donor 1 → donor 2; donor 2 → acceptor; donor → acceptor are addressed qualitatively and quantitatively. For the artificial special pairs flanked with an antenna, the effect of the spacer between the artificial special pair and the antenna will be discussed as well as the choice of substituents and metal demonstrating that one can reverse the orientation of the singlet energy transfer: artificial special pair → side arm or side arm → artificial special pair. Finally, the antenna effect are presented for one example of artificial special pair equipped with 6 semi-flexible dendritic antennas.

Resumen
Les pérovskites halogénées (PHs) sont apparues comme une nouvelle classe de matériaux semiconducteurs très prometteurs pour des applications en photovoltaïque et optoélectronique. Ces matériaux présentent des propriétés remarquables telles qu'un long temps de vie et une importante longueur de diffusion des porteurs de charge malgré une densité de défauts élevée. Cependant, l'origine physique de la tolérance aux défauts des PHs est encore très débattue. Une meilleure compréhension de la nature et de l'impact des défauts est encore nécessaire pour optimiser les dispositifs. De plus, de part notamment un fort couplage spin-orbite, les PHs sont aussi prometteuses pour des applications en spintronique. Cependant, la compréhension des propriétés de spin des PHs doit être encore être approfondie. Les monocristaux de PHs obtenue par croissance en solution sont aujourd'hui le meilleur système pour explorer les propriétés intrinsèques des PHs.Dans cette thèse, nous avons étudié les propriétés optiques et de spin des cristaux de l'archétype des pérovskites 3D, CH3NH3PbI3. Dans une première partie, nous avons étudié l'émission des défauts de CH3NH3PbI3 en microscopie et spectroscopie de luminescence à basse température. La dépendance en fonction de la puissance d'excitation, la dynamique temporelle et l'évolution en température de l'émission sont analysés. L'ensemble des résultats est cohérent avec un processus de recombinaison de paires donneurs-accepteurs (DAP). En particuliers, la signature de transitions DAP discrète, sous la forme de séries de raies fines, avec des largeurs inférieures au meV est mise en évidence.Dans une deuxième partie, des mesures d'excitation de la photoluminescence sont réalisées pour étudier les processus de relaxation des porteurs de charge et des excitons dans CH3NH3PbI3. La transition excitonique intrinsèque n'est que faiblement impliquée dans la relaxation vers l'émission des défauts. Par contre, les mesures révèlent l'existence d'un canal d'excitation très efficace des DAP à une énergie de 1.633 eV, inférieure de 20 meV à la bande interdite. Un mécanisme d'excitation est proposé reposant sur une transition bound-to-free. De plus, l'étude de la polarisation de l'émission montre que les raies fines peuvent présenter un degré de polarisation linéaire important, jusqu'à approximativement 40%. Cette mesure pointe vers une orientation préférentielle des dipôles des DAP au sein du cristal.Dans une troisième partie, nous montrons que les raies fines de CH3NH3PbI3 présentent de la diffusion spectrale (SD). L'absence de dégroupement de photon de l'émission indique cependant que la SD n'est pas associée à un émetteur de photon unique. L'analyse des corrélations entre la SD de plusieurs groupes de raies démontre qu'un ensemble de défauts peuvent faire l'expérience des mêmes fluctuations. Un comportement qui peut être relié à la présence de domaines à basse température au sein du cristal.Finalement, les propriétés de spin de CH3NH3PbI3 sont étudiées. Un dispositif optique a été développé pour contrôler la polarisation de la lumière en excitation et collection. En l'absence de champ magnétique, deux émissions linaires pratiquement orthogonales sont mises en évidence et associées aux états excitoniques brillants de CH3NH3PbI3. Sous l'effet d'un champ magnétique longitudinal, à 9 T, un degré de polarisation circulaire (DCP) de 50% est mesuré. Par ailleurs, des mesures d'orientation optique en excitation continue conduisent à un DCP de 55%. Ces observations mettent en évidence un relativement long temps de relaxation de spin d'approximativement 300 ps dans les cristaux de CH3NH3PbI3
Halide perovskites have emerged as a promising new class of semiconductor materials for photovoltaic and optoelectronic applications. They present remarkable optoelectronic properties such as long carrier lifetime and diffusion length despite a high defect density. However, the underlying physical origin of the defect tolerance of HPs is still debated. A better understanding of the nature and impact of defects is still required in order to optimize further the devices. Additionally, with a strong spin orbit coupling, HPs are also promising for applications in spintronics. The investigation of the spin properties of HPs is just beginning. Solution-grown single crystals are to date the best system to explore the intrinsic properties of HPs.In this PhD, we investigate the optical and spin properties of single crystals of the archetypal 3D perovskite, CH3NH3PbI3. In a first part, we study the defect emission of CH3NH3PbI3 based on low temperature photoluminescence microscopy and spectroscopy. The excitation power dependence, time dynamics and temperature evolution of the defect emission is analysed. Series of sharp DAP lines with sub-meV width, the fingerprint of discrete DAP transition, are in particular observed.In a second part, PL excitation spectroscopy is used to study the relaxation pathway of carriers and excitons in CH3NH3PbI3 single crystals. The intrinsic free excitonic transition is only weakly involved in the relaxation toward the defect emission, and with no apparent contribution to DAP emission at low energy. In contrast, the results reveal the existence of a very efficient excitation of the DAP transition with below the band gap excitation at 1.633 eV. A strong enhancement of the defect emission is reported for both the broad band emission and the sharp luminescence lines. An excitation mechanism is proposed based on a bound-to-free transition. Then, the polarization of the sharp defect lines is studied and shows the existence of a significant degree of linear polarization of approximately 40% for several lines. The polarization of the defect lines can be interpreted as the indication of a preferential orientation of the DAP dipoles.In a third part, we shows that spectral diffusion can be observed in the sharp line emission of CH3NH3PbI3. The absence of antibunching indicates that the SD is not associated with single photon emission. The analysis of correlations in the SD of groups of PL lines shows that an ensemble of independent defects can experience the same fluctuations.Finally, we investigate the spin properties of CH3NH3PbI3. An optical set-up has been developed to control the polarization of light in both excitation and collection. In the absence of magnetic field, we measure two nearly orthogonal linearly polarized emission which can be associated to the bright excitonic states. An important degree of field-induced circular polarization of 50% is evidenced. Optical orientation under CW excitation lead to a degree of circular polarization of 55%. These results allow us to estimate the spin relaxation time to approximately 300 ps in CH3NH3PbI3 single crystals

Resumen
Multi-step photoinduced electron transfer takes place over a large distance in the photosynthetic reaction centres (PRCs). Electron donor in this life-spending event is the photo-excited 'special pair', a unit of two electronically coupled porphyrinoid chromophores. Bacteriopheophytin and two quinone molecules function as electron acceptors and contribute to the charge separation with almost unit quantum efficiency. The natural photosynthetic reaction centre is the most sophisticated molecular electronic device to date and interest is high in increasing our understanding of the basic quantum mechanical principles behind efficient electron transfer and ultimately copying Nature and construct similar efficient devices. Two main approaches towards a better understanding of the mechanisms involved have been taken. The more biological disciplines isolate, cultivate and alternate reaction centres whereas synthetic chemists prefer to construct well-defined models that mimic certain aspects of the reaction centres. Such a synthetic approach is described in the 'Synthesis of Advanced 'Special Pair' Models for the Photosynthetic Reaction Centre'. The aspect to be mimicked is the 'special pair'. One or two porphyrins in a well-defined spatial disposition (kinked or non-kinked in respect to each other) were to act as electron donor in rigid bichromophoric and trichromophoric systems. A tetracyanonaphthoquinodimethane (TCNQ) unit was employed as the electron acceptor in the series of dyads synthesised. The TCNQ acceptor was replaced by a naphthoquinone (NQ) primary acceptor covalently linked to a TCNQ secondary electron acceptor in the series of triads. Rigid norbornylogous bridges held the chromophores in place and Diels-Alder methodology as well as condensation reactions were applied to link donor, bridge and acceptor components. Despite larger interchromophoric separation than in the natural 'special pair', the two porphyrin chromophores of the series of 'special pair' dyads show some interaction and thereby prove the success of our approach towards 'special pair' mimics. Strong fluorescence quenching in the porphyrin-TCNQ dyads indicates the sought after electron transfer process. A number of synthetic problems experienced and overcome in the synthesis of the series of triads led to discovery of a one-step 'bis-ketonisation' from an olefin under Sharpless bis-hydroxylation conditions with N-methylmorpholine-N-oxide. High pressure was applied to circumvent a lack of reactivity in the condensation reaction used to attach the porphyrin moieties (one or two) to the donor backbone. For the linkage of donor, bridge and acceptor component, a procedure was developed and successfully applied to give the giant mono-porphyrin-NQ-TCNQ trichromophore. In a similar manner 'special pair' trichromophoric systems should be available as part of future work.

Resumen
En raison des problèmes d'instabilité à moyen termes des cellules solaires à colorant (DSSC), l'électrolyte liquide à base d'iodure a été remplacé par plusieurs types de matériaux solides transport de trous (HTM) pour obtenir des DSSCs à l'état solide (s-DSSCs). Parmi ces matériaux, l’utilisation des polymères conducteurs(PC) a attiré une attention considérable en raison de leur bonne stabilité, de leur haute conductivité et de la facilité de leur dépôt sur le semi-conducteur mésoporeux TiO2. Dans ce travail de thèse, plusieurs s-DSSCs basées sur des PC utilisés comme HTM ont été développés dans le but d'améliorer leurs performances photovoltaïques en tenant compte des deux objectifs suivants: (i) l'optimisation des processus de transfert inter facial de charge dans la cellule solaire, et (ii) l'optimisation du transport de charge dans le semi-conducteur d'oxyde de type n. Pour atteindre ces objectifs, chaque composant de la s-DSSC a été modifié afin d'étudier son effet sur les performances du dispositif final. En première tentative, une étude analytique est réalisée en faisant varier le sensibilisateur afin de déterminer les fragments de la structure du colorant, qui ont un effet important sur le processus de photopolymérization électrochimique in-situ (PEP) à la fois en milieu organique et en milieu aqueux mais aussi sur les performances des s-DSSCs. Sur la base de ces résultats, un nouveau concept a été développé et consiste en la suppression totale de l'interface entre le colorant et le HTM. Ceci est obtenu par la synthèse de nouveaux colorants liés de façon covalente à un monomère électroactif qui est co-polymérisé par la PEP in-situ. Le copolymère résultant, utilisé comme HTM, est lié de manière covalente au colorant. En outre, la nature de la liaison chimique, reliant le résidu triphénylamine TPA au monomère, est également étudiée comme un facteur clé dans les performances de s-DSSC. En outre, et pour optimiser les processus de transport de charges dans ce type de s-DSSC, de nouvelles s-DSSC basées sur ZnO ont été réalisées et étudiées
Due to instability problems of dye sensitized solar cells (DSSCs) in longtime uses, the iodine based liquidelectrolyte has been replaced by several types of solid hole transporting materials (HTM) to perform solidstate DSSCs (s-DSSCs). Among them, the substitution by conducting polymers (CP) has attractedconsiderable attention because of their good stability, high hole-conductivity and simple deposition withinthe mesoporous TiO2 semiconductor. In this thesis work, several s-DSSCs based on CPs used as HTM havebeen developed in order to improve their photovoltaic performances taking into account the following twoobjectives: (i) the optimization of the interfacial charge transfer processes within the solar cell, and (ii) theoptimization of the charge transport within the n-type oxide semiconductor. To reach these goals, eachcomponent that constitutes the device was varied in order to investigate its effect on the device’sperformances. As first attempt, an analytical study is carried out by varying the sensitizer in order todetermine the fragments of the dyes structures, that have an important effect on the in-situ photoelectrochemical polymerization process (PEP) both in organic and in aqueous media and hence on theperformances of the s-DSSCs. Based on these results, a new concept of removing completely the interfacebetween the dye and the HTM is developed. This is achieved by the synthesis of new dyes covalently linkedto an electroactive monomer which is co-polymerized by in-situ PEP. The resulting co-polymer, used asHTM, is covalently linked to the dye. In addition, the nature of the chemical bond linking the triphenylamineresidue TPA to the monomer is also investigated as a key factor in the s-DSSCs performances. Besides, andto optimize the charge transport processes within this type of s-DSSC, the elaboration of novel ZnO baseds-DSSCs has been achieved and investigated

Resumen
This paper reports the first ultrafast studies on the rates of DNA-mediated forward and reverse electron transfer between photoexcited [M(phen)2dppz]2+ (M=Ru or Os, phen =1,10-phenanthroline, dppz = dipyrido[3,2:a-2′,3′:c]-phenazine) and various electron acceptors in order to ultimately determine the distance dependence of electron transfer kinetics with DNA as an environment.1,2 Previously Barton, Turro, and coworkers have presented evidence that electron transfer in DNA can occur rapidly over an extraordinarily large distance3 with a more shallow distance dependence than that for other media, such as liquids and proteins.4,5 Some theoretical work supports the shallow distance dependence which is attributed to a long range, thermally activated coherent mechanism involving virtual excitation of the DNA "bridge".6 Utilizing time-correlated single photon counting (TCSPC), we observe a substantial fraction of photoexcited [M(phen)2dppz]2+ (M=Ru, Os) exhibits fast oxidative quenching (kq > 3 x 1010 s−1) in the presence of intercalating Rh(III) acceptors while the remaining excited-state species exhibit a range of quenching constants less than 108 s_1. Transient-absorption experiments on the picosecond timescale indicate that, for a series of donors bound to mixed sequence DNA, the majority of back electron transfer is also very fast (ca. 1010 s−1). Importantly, the rate constant for the fast ground-state recovery is independent of loading of Rh(III) intercalators on DNA. As shown in Figure 1, regardless of whether the average loading of metal complexes is 1 in 33 basepairs or 1 in 10 basepairs, the fast bleach recovery exhibited by [Ru(phen)2dppz]2+ is well fit under all conditions by an exponential decay of 9 x 109s−1. Separate ultrafast data suggests that, like the recombination reaction, the fast quenching *M2+ is simple first-order at early time. If the early time electron transfer kinetics were not simple first order, and the electron transfer rate decayed with an exponential distance dependence (i.e. ≅ a factor of 30 per base step [3.4 Å]), our TCSPC apparatus should be able to observe some evidence of the slower components with rate constants in the range of 1010 - 108 s−1. The absence of rates in this range is evidence that the electron transfer is simple first order at time < 10 ns. This result has implications with regards to the donor-acceptor separations on DNA. Throughout most of the titration, intercalators are dilute on the double helix and statistics show that the amount of fast quenching and ground-state recovery observed is too great to be accounted for by random loading of nearest-neighbor pairs. Thus, either the electron transfer reaction must involve clustering of the donor and acceptor on the helix or the DNA-mediated interaction must occur over long distance.
