Synthèse et valorisation de ligands dipyrrométhène bis-triazole

Abstract : Known as structural analogues of porphyrins and Salens, dipyrromethene bis-phenol-type ligands have been studied in our group, especially as complexes for oxidation catalysis. Due to the poor catalytic activity of these complexes, it has been proposed to replace the phenol moieties with triazoles. The purpose of this thesis was to study and develop a new family of dipyrromethene bis-triazole ligands.Several synthetic routes were first investigated and optimized to reach these new ligands. We then have endeavoured to add value to these new ligands along several lines.The ligand has been tested in anion recognition, as well as monotriazolium and bis-triazolium derivatives. The triazoliums also allowed access to carbene metallocomplexes that were studied.Furthermore, dipyrromethene bis-triazole metallocomplexes were prepared and characterized, notably by electrochemistry. Oxidation catalysis tests were undertaken.Finally, the synthesis of liposoluble and hydrosoluble BODIPYs® was performed. Their optical properties were measured and these fluorescent derivatives were tested for the fluorescent labeling of HeLa cells
