Abstract:
A series of [26]hexaphyrins(1.1.1.1.1.1) bearing two α-oligothienyl substituents at 5,20-positions have been synthesised and are shown to have a dumbbell hexaphyrin conformation, to which the α-oligothienyl groups are linked to form an acyclic helix-like conjugated network.

Abstract:
Corroles and hexaphyrins are porphyrinoids with great potential for diverse applications. Like porphyrins, many of their applications are based on their unique capability to interact with light, i.e., based on their photophysical properties. Corroles have intense absorptions in the low-energy region of the uv-vis, while hexaphyrins have the capability to absorb light in the near-infrared (NIR) region, presenting photophysical features which are complementary to those of porphyrins. Despite the increasing interest in corroles and hexaphyrins in recent years, the full potential of both classes o

Abstract:
Contrairement à l'aromaticité de Hückel classique, peu de choses sont connues sur les aromaticités dites « non orthodoxes » (c'est-à-dire l'antiaromaticité de Hückel et l'aromaticité de Möbius) en raison de leur totale absence dans la nature et de la difficulté à les synthétiser. Par conséquent, peu d'études ont été menées pour explorer les interactions de type π impliquant ces aromaticities non orthodoxes. Cependant, ces caractéristiques se retrouvent dans la famille des dérivés porphyrinoïdes, en particulier les hexaphyrines, qui peuvent alternativement adopter un caractère Hückel antiaromat

Abstract:
Les hexaphyrines sont des macrocycles constitués de six unités pyrroliques, elles possèdent des propriétés physico-chimiques intéressantes, dont notamment leur capacité à exister sous deux états oxydés stables, à 26 et 28 électrons π délocalisés. Elles peuvent coordonner jusqu’à deux cations métalliques au sein du macrocycle, cependant elles souffrent d’un manque de réactivité et de prédictibilité quant à la nature des complexes formés. Pour pallier à ces problèmes, nous avons décidé de suivre une stratégie de post-modification du macrocycle, mettant en jeu l’incorporation sans précédent d’un

Abstract:
Les hexaphyrines sont constituées de six unités pyrroliques et présentent différents types d'aromaticité, à l'origine de leurs remarquables propriétés de coordination. Cependant, les complexes sont décrits majoritairement sur des hexaphyrines « nues ». De plus, l'induction de chiralité sur un anneau de Möbius n'en est qu'à ses prémices. Dans ce contexte, nous explorons les propriétés de coordination des hexaphyrines « chapeautées ». Plus particulièrement, notre objectif consiste à élaborer des ligands hybrides, dont les unités hexaphyrine et cyclodextrine sont liées de manières covalentes. Pou

Abstract:
Pyrrole moiety forms many naturally occurring biologically active compounds and exist in the structure of some biologically active compounds. From this point of view, pyrrole derivatives are very important building blocks in the drug industry and so in organic syntheses. Dipyrromethane derivatives are the building blocks for the syntheses of a variety of calix[n]pyrroles, porphyrins, hexaphyrin and polypyrrolicmacrocycles. The oxidized dipyrromethane derivatives (i.e. dipyrromethenes or dipyrrins) have strong coordinating ability towards different metal ions and their metal complexes with triv
