Highly efficient blue phosphorescent organic light emitting diodes have been developed using novel sulfone-based electron transport materials (SPDP, SPDQ, and SPPP) with high triplet energy. The blue phosphorescent devices combine high quantum efficiency (19.6%) with high current efficiency (33.6 cd A−1).
已开发出高效率的蓝色磷光有机发光二极管,使用了具有高三重态能量的新型磺酮基电子传输材料(SPDP、SPDQ和SPPP)。这些蓝色磷光器件结合了高量子效率(19.6%)和高电流效率(33.6 cd A−1)。
