2,2'-bis(4-(carbazol-9-yl)phenyl)-biphenyl (BCBP) has a bridged biphenyl structure with two electron rich carbazolyl pendant moieties. The bridged structure is believed to enhance the conjugation and raise the HOMO energy level,?facilitating hole-injection and leading to low turn-on voltages in organic photoelectroluminescent devices.
