Abstract

A trigonal donor-acceptor molecule of 1,3,5-tris(4-(diphenylamino)phenyl)-2,4,6-tricyanobenzene (3DPA3CN) was synthesized to exhibit efficient thermally activated delayed fluorescence. By doping 3DPA3CN into a wide energy gap host, the film had a photoluminescence quantum efficiency of 100% with the reverse intersystem crossing efficiency of 100%. An OLED including the emitter exhibited a very high external quantum efficiency (η(EQE)) of 21.4%.
