9,9'-Diphenyl-9H,9'H-3,3'-bicarbazole (BCzPh), with two conjugated carbazole units, is an electron-rich host material used for phosphorescent organic light-emitting diodes (PHOLEDs). Being electron-rich, BCzPh is also used as an electron donor to form exciplexes either as an emitting layer or host material for highly-efficient fluorescent and phosphorescent OLED devices.
With the dimerisation of carbazoles (and thus the blocked 3 and 3') positions, BCzph can greatly reduce the host-host aggregation, causing excimer formation. With a higher Tg, it can also improve thermal and morphological stability of thin films.
