合成了一种1，3，5-tris(4-(diphenylamino)phenyl)-2，4，6-tricyanobenzene的三角供体-受体分子(3DPA3CN)，表现出高效的热激活延迟荧光。通过在宽禁带基质中掺杂3DPA3CN，薄膜的光致发光量子效率为100%，反向系间交叉效率为100%。包括发射极的OLED显示出非常高的外量子效率(ETA(EQE))，达到21.4%。
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 (eta(EQE)) of 21.4%.
