Synthèse et étude de complexes de métaux de transition pour de nouveaux matériaux à applications photovoltaïques

Abstract : Terpyridine ligands are prepared. These ligands are functionalised at position 4' either by heterocycles such as furan, thiophene and pyrrole, or by a carboxylic acid (or a precursor).To prepare these compounds, a new method using alumina as a base without solvent is used. These ligands are used in the preparation of ruthenium (II) complexes. Two kinds of complexes are prepared : homoleptic complexes in which both ligands are functionalised by an heterocycle, and heteroleptic ones in which one ligand is functionalised by an heterocycle, and the other one by carboxylic acid function. For the latter, a new access is presented. It is based on the oxidation of a furan ring into a carboxylic acid, directly on the complex. Photo-physical and electrochemical properties of these complexes are studied. These complexes are also used in preparation of new materials. Homeleptic ones allow preparation of oligomers containing metallic centres by electro-polymerisation. Heteroleptic ones are used in the preparation of modified electrodes by covalent bonding with the carboxylic acid function.
