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.

摘要

铑(III)配合物很少显示强磷光，这与众所周知的具有环金属配体的铱(III)配合物形成对比。本研究展示了 1,3-双(1-异喹啉基)苯如何通过 N^C^N 配位环金属化到 Rh(III)上，从而在室温下得到具有前所未有的磷光量子产率的配合物。还描述了它们高发光的 Ir(III)类似物。
