Abstract

Novel cationic cyclometallated Ir (III) complexes bearing diaza-or monoazafluorene substituted or not with a C60-fullerene moiety have been synthesized together with a novel interesting ligand 9-fulleriden-4-monoazafluorene and the related Ir (III) neutral complex [Ir (ppy) 2 (9-fulleriden-4-monoazafluorene)]. All complexes show a negative large value of μβ1. 907 (− 600 to− 2190× 10− 48esu), as determined by the Electric Field Induced ...
