Abstract

A high efficiency deep blue phosphorescent organic light-emitting diodes was developed using an weak electron transport type high triplet energy host material with dibenzofuran and phosphine oxide units. The host material showed a high triplet energy of 3.01 eV and was effective as the host material for deep blue phosphorescent organic light-emitting diodes. The device performances could be optimized by managing the doping concentration of phosphorescent dopants and a high quantum efficiency of 25.9% with a color coordinate of (0.14, 0.22) was achieved.
