Abstract

Benefitting from short-range charge transfer (SR-CT) and through-space charge transfer (TSCT) effects, an efficient green narrowband emitter, BNDCN, was developed. Owing to the synergistic effect of double CT processes, a BNDCN-based organic light-emitting diode showed a high external quantum efficiency of 32.3%.
