σ–π and p–π conjugation induced NIR-emitting iridium(<scp>iii</scp>) complexes anchored by flexible side chains in a rigid dibenzo[<i>a</i>,<i>c</i>]phenazine moiety and their application in highly efficient solution-processable NIR-emitting devices

Abstract

The σ–π and p–π conjugation effects of Ir(<sc>iii</sc>) complexes are systematically investigated by simply adjusting the flexible side chains.
