Bis(phosphine oxide)/triphenylamine based material for solution-processed blue electrofluorescent and green electrophosphorescent devices†
Abstract
A novel material TPA-BPhPO with a photoluminescence quantum yield of 68% and a triplet energy of 2.48 eV has been designed and synthesized. High external quantum efficiencies of 1.41% and 9.3% were achieved in solution-processed blue electrofluorescent and green electrophosphorescent devices, respectively.
