The synthesis and luminescence properties of new platinum and iridium complexes

The work of this thesis is focused on the synthesis and the photoluminescence studies of new 3 raw transition metal complexes (Ir(III), Pt(II), Pd(II)) . The main objective is to obtain new phosphorescent materials for applications such as organic light emitting diodes (OLEDs) and bio- imaging. The incorporation of chromophores such as pyrene and naphthalimide into fac-Ir-(thpy)3 complex will first be presented. The synthesis, by C–H activation, of the new complex will also be studied. New ultra-rigid organometallic complexes will then be developed. The synthesis and the photoluminescence analysis of these tetradentate platinum and palladium complexes will be described. Finally, a study of new iridium complexes incorporating benzimidazoles (iso)-quinoline and bis-benzimidazole ligands sensitive to pH variations will be made
