A versatile thermally activated delayed fluorescence emitter for both highly efficient doped and non-doped organic light emitting devices

A thermally activated delayed fluorescent (TADF) emitter (DMAC-TRZ) was reported either as the emitting dopant in a host or as the non-doped (neat) emitting layer to achieve high EL EQEs of up to 26.5% and 20% in OLEDs, respectively.
