Synthesis and Characterization of Iridium(III) Complexes with Substituted Phenylimidazo(4,5-f)1,10-phenanthroline Ancillary Ligands and Their Application in LEC Devices.

ABSTRACT: In this work, we report on the synthesis and characterization of six new iridium(III) complexes of the type [Ir(C^N)₂(N^N)]⁺ using 2-phenylpyridine (C1-3) and its fluorinated derivative (C4-6) as cyclometalating ligands (C^N) and R-phenylimidazo(4,5-f)1,10-phenanthroline (R = H, CH₃, F) as the ancillary ligand (N^N). These luminescent complexes have been fully characterized through optical and electrochemical studies. In solution, the C4-6 series exhibits quantum yields (Ф) twice as high as the C1-3 series, exceeding 60% in dichloromethane and where ³MLCT/³LLCT and ³LC emissions participate in the phenomenon. These complexes were employed in the active layer of l
