title: Bright orange/red-emitting rhodium(III) and iridium(III) complexes: tridentate N^C^N-cyclometallating ligands lead to high luminescence efficiencies.
abstract: Rhodium(III) complexes rarely display strong phosphorescence, in contrast to well-known iridium(III) complexes with cyclometallating ligands. This study shows how 1,3-bis(1-isoquinolyl)benzene cyclometallates to Rh(III) through N^C^N-coordination to give complexes with unprecedented phosphorescence quantum yields at room temperature. Their highly emissive Ir(III) analogues are also described.
