Novel blue fluorescent emitters structured by linking triphenylamine and anthracene derivatives for organic light-emitting devices with EQE exceeding 5%

Two novel bipolar compounds of TPA-AN-NA and TPA-AN-TFP were designed by linking triphenylamine and anthracene derivatives. The TPA-AN-NA-based blue device achieves a high external quantum efficiency of 5.44% and a radiative exciton yield of 56.68%.
