- Abstract
- Luminescence phenomena have fascinated mankind for centuries. The ability of a system to emit light is widespread in nature especially in deep-ocean. The scientific understanding of light emission has led to impressive improvements these last years. As a result, Light-Emitting Materials have recently emerged virtually everywhere. The material composition is variable. However, Iridium-based complexes have been frequently used for a couple of years in order to benefit from their easy color tunability. The usual complexes bear three bidentate ligands. However, the structure and properties of two tridentate ligands-based complexes display some advantages which have been too scarcely used to develop some innovating applications. During this Ph.D. thesis, we have studied the spectroelectrochemical properties of some novel luminescent Ir(III) complexes chelated by two tridentate ligands. By modifying the coordination sphere, the properties of the resulting assemblies can be modulated and compared one to another. Based on this study, the synthesized Ir(III) derivatives have been exploited as photocatalysts for both organic reactions and reduction of protons into molecular hydrogen. In addition, the studied Ir(III) complexes can successfully act as DNA photo-probes. Finally, a new methodology to reach functionalized multi-terdentate ligands has been explored.
