Abstract:

Die Ziele dieser Arbeit waren die Darstellung der Naturstoffe Murrayachinon-B–E und Pyrayachinon-A–C, sowie die Synthese einiger nicht natürlicher, potentiell anti-Tuberkulose-aktiver Carbazole und Carbazolchinone. Für die Darstellung der aus der Pflanze Murraya euchrestifolia Hayata isolierten Naturstoffe wurden verschiedene synthetische Herangehensweisen untersucht: Die Transformation eines 7 Hydroxycarbazolchinons in die Zielverbindungen gelang nicht, ebenso wie die Syntheseroute über eine trioxygenierte Vorstufe. 7-Methoxy-3-methyl-1-tosyloxycarbazol (A) ließ sich jedoch in einer Ausbeut

The used amines are modified carbazoles with functional groups chosen to amplify or disempower the steric and the conjugation effect. We have found that the evaluation of steric barrier was possible studying the gearing aryls rotation around the C-B bonds, while the conjugation barrier is instead given by the energy needed to break t

Abstract:

Unprecedented Ullmann couplings of murrayafoline-A with either 6-bromo- or 4-bromocarbazole derivatives provide highly efficient synthetic routes to the biscarbazole alkaloids murrastifoline-A (6 steps, 66% overall yield) and bismurrayafoline-A (6 steps, 28% overall yield).<br>Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Abstract:

Ce travail a consisté à élaborer de nouveaux verres moléculaires transporteurs de trou dérivés du carbazole pour remplacer le spiro-OMeTAD (matériau de référence) dans les cellules solaires hybrides à colorant tout solide. Nous avons synthétisé différents dérivés du carbazole 3, 6, 9 substitués, établi leurs principales propriétés physico-chimiques et les avons utilisés en DSSC solide. Nous avons mis en évidence l'intérêt de greffer des groupements bis(4-méthoxyphényl)amines en positions 3, 6 et des aryles en position 9 du carbazole pour obtenir des matériaux performants. Finalement, cette str

Cette thèse porte sur la synthèse et la caractérisation de nouveaux semi-conducteurs organiques à base de carbazole et d'indolo[3,2-b]carbazole. La synthèse de petites molécules et de polymères a été accomplie dans le but de fabriquer des transistors organiques à effet de champ (TOECs). Plusieurs techniques de mise en oeuvre ont été utilisées pour déposer les films et obtenir les meilleures performances possibles. Tout d'abord, l'évaporation sous vide des petites molécules a permis d'obtenir des films avec un haut degré de cristallinité, qui furent analysés par diffraction des rayons-X (DRX) e

Abstract:

Seven naturally occurring pyranocarbazole alkaloids (pyrayafoline A–E, O-methylmurrayamine A and O-methylmahanine) have been obtained by total synthesis using a palladium(II)-catalysed oxidative cyclisation of a diarylamine to an orthogonally diprotected 2,7-dihydroxycarbazole as key step.

Abstract:

The electropolymerisation of a range of 5-substituted indoles has been shown previously to result in the formation of redox-active films. The oxidation potentials of both the indole monomers and their polymers can be altered by substitution of the monomer with different electron-withdrawing groups. Both the indole monomers and polymers also have high fluorescence quantum yields. However the fluorescence wavelengths of the indole polymers are not tuneable by substitution. In this thesis the work on the electropolymerisation of indole(s) is extended to two monomers which have larger conjugated s

Abstract:

Le travail porte sur la synthèse, la caractérisation et l'étude des propriétés des polyesters à groupes carbazoliques n-substitues dans la chaîne. La première étape du travail à consisté à mettre au point la synthèse des monomères: les acides n-alkylcarbazole-3,6-dicarboxyliques (alkyl = butyl et octyl). Dans un deuxième temps, la synthèse en masse des polyesters a été réalisée, selon deux procédés: continu (a partir des diacides correspondants et de l'éthylène glycol) et discontinu (a partir du diester isole). La solubilité de certains des polyesters préparés a permis d'étudier la cinétique d
