Abstract

A novel binuclear Cu(I) halide complex, Cu₂I₂(DPPCz)₂, which emits efficient thermally activated delayed fluorescence (TADF), is reported. The crystal of this complex spontaneously undergoes ligand rotation and coordination-configuration transformation, converting to its isomer without any external stimulation.
