Abstract

Two host materials, 9-(3''-(9H-carbazol-9-yl)-[1,1':2',1''-terphenyl]-3-yl)-α-carboline (CzOTCb) and 3,3''-bis(α-carbolin-9-yl)-1,1':2',1''-terphenyl (CbOTCb), derived from carboline and ortho-linked terphenyl were synthesized as high triplet energy materials and showed a high triplet energy of 2.90 eV. CzOTCb and CbOTCb were evaluated as the host materials for blue phosphorescent organic light-emitting diodes and high quantum efficiencies of 27.4% and 28.8% were obtained using the CzOTCb and CbOTCb hosts, respectively.

摘要

两种主体材料，9-(3''-(9H-咔唑-9-基)-[1,1':2',1''-三联苯]-3-基)-α-咔啉（CzOTCb）和 3,3''-双（α-咔啉-9-基）-1,1':2',1''-三联苯（CbOTCb），由咔啉和邻位连接的三联苯衍生而来，被用作高三重态能量材料，表现出 2.90eV 的高三重态能量。CzOTCb 和 CbOTCb 被评估为蓝色磷光有机发光二极管的主体材料，使用 CzOTCb 和 CbOTCb 主体材料分别获得了 27.4%和 28.8%的高光量子效率。
