Title: FLUORENO CARBAZOLE DERIVATIVE AND PHOSPHORESCENT ORGANIC ELECTROLUMINESCENT DEVICE
Abstract:
A fluoreno carbazole derivative and a phosphorescent organic electroluminescent device using same. The fluoreno carbazole derivative is represented by general formula I. Fluoreno carbazole is used as a core, carbazole and spirobifluorene are combined, so that the loss of triplet state energy is reduced, and the hole mobility and Tg of the derivative are not changed.
