We have designed and synthesized a new family of neutral phosphorescent iridium(III) complexes (- featuring three differently charged (0, -1, and -2) ligands, in which biphenyl () is used as a dianionic (-2) ligand, 4,6-difluorophenylpyridine () or 1-phenylisoquinoline () is used as a monoanionic (-1) ligand, and 2,2'-bipyridyl (), 1,10-phenanthroline (), 1,2-bis(diphenylphosphanyl)benzene (), or 1,2-bis(diphenylphosphanyl)ethane () is used as a neutral (0) ligand. The X-ray structures confirm that three coordination carbon atoms of all complexes assume a facial geometry, which can be beneficial to the stability of the structure. More importantly, the emitting color of the complexes can be tuned from deep red/near-infrared (NIR) (680-710 nm) to blue-green (466-496 nm) with different monoanionic (-1) ligands and neutral (0) ligands.
