Thin Film Electrodeposition of Ir(III) Cyclometallated Complexes

Novel electropolymerizable ir(iii) cyclometallated complexes have been synthesized and characterized. in these complexes the cyclometallated ligands are either 2-phenylpyridine h(phpy) or benzothiazole-triphenylamine h(bzth-tpa),while the ir(iii) coordination sphere is completed by a schiff base substituted with a triphenylamine fragment. a complete electrochemical study has been conducted on all complexes,in order to verify the feasibility of electropolymerization and to elucidate the role of the specific position of the triphenylamine moiety in the molecular structure. homogeneous thin films of ir(iii) metallopolymers have been successfully obtained through electropolymerization process. © 2016 andreea ionescu et al.
