Abstract

Carbene coinage metal carbazolates are currently the most efficient organometallic TADF emitters. Herein we report on the photophysical influence of introducing a [2.2]paracyclophane moiety via a carbazolophane ligand instead of carbazolate, which greatly enhances the radiative rate constants by a factor of three to 1-3·106 s-1 for triplet exciton emission.
