Blue Phosphorescent

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).
