Bis-4-(N-carbazolyl)phenyl)phenylphosphine oxide - BCPO - is a bipolar host material containing phenylphosphine oxide as an electron withdrawing moeity and two carbazolyl groups as electron donating moieties. BCPO possesses a high triplet energy (ET ) of 3.01 eV and a high glass transition temperature (Tg) of 137 °C. The phosphine oxide moiety in the middle of the structure can effectively cut off the electron communication between the two N-phenyl carbazole groups, leading to a much higher triplet energy of BCPO than CBP.
Like CBP and mCBP, BCPO can be used as a universal host to blue, green and red fluorescent and phosphorescent devices using simple device architectures.
