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.
BCzPh is an isomer of CBP and mCBP which are used as universal host materials for blue, red, green and white electroluminescent OLED devices.
*Sublimation is a technique used to obtain ultra pure-grade chemicals. For more details about sublimation, please refer to the Sublimed Materials for OLED devices page.
