FLUORENE-CARBAZOLE DERIVATIVES AND PHOSPHORESCENT ORGANIC ELECTROLUMINESCENT DEVICES

摘要

The present disclosure provides fluorene-carbazole derivatives and phosphorescent organic electroluminescent devices using the fluorene-carbazole derivatives. The fluorene-carbazole derivative is represented by General Formula I. In the present disclosure, fluorene-carbazole is the core, spirobifluorene is combined with carbazole to reduce the loss of triplet energy without a change in hole mobility and Tg.
