We designed and synthesized a new organic light-emitting diode (OLED) emitter, SBABz4, containing spiro-biacridine donor (D) in the core surrounded by two benzonitrile acceptors (A). The dual A–DxD–A structure is shown to provide pure-blue emission in relation to its single A–D counterpart. Time-res...
