Synthèses et propriétés photophysiques de nouveaux complexes hétérométalliques de platine(II)-iridium(III) et leurs polymères
Soliman, Ahmed M
Platinum(1I) and charged cationic iridium(III) complexes have attracted great interest as luminophores in a myriad of applications. Notably, each class of these complexes has been incorporated into organic light emitting diodes (OLEDs), light-emitting electrochemical cells (LEECs), nonlinear optical materials and photovoltaic devices. This thesis reports the synthesis of hybrid Pt-Ir-containing organometallic complexes and polymers with the goal of obtaining high performance luminophores for electroluminescent devices. As a first step towards the polymer construction, the synthesis of a series of homometallic and heterometallic monomeric complexes has been performed. A survey of the synthesis and detailed photophysical characterization of the polymer and their model monomers are reported. Comparison of the spectroscopic signature of the complexes state are hybrids between the metal-to-ligand charge transfer ([superscript 1]MLCT and [superscript 3]MLCT) of the [Ir(bp[gamma])(pp[gamma])[subscript 2]+ and [trans-Pt(CCAr)[subscript 2](PBu[subscript 3])[subscript 2] chromophores. This conclusion is supported by computational studies, DFT (density functional theory) and TDDFT (time-dependent density functional theory).
