2,2'-bis(4-(carbazol-9-yl)phenyl)-biphenyl

Description

2,2'-bis(4-(carbazol-9-yl)phenyl)-biphenyl (BCBP) can be used as the host material for blue, green, and red phosphorescent dopants for the synthesis of OLED devices. Compared to 4,4'-(bis(9-carbazolyl)) biphenyl (CBP), the glass transition temperature of BCBP is higher, about 173°C. Therefore, the thermal stability of BCBP is excellent.
