It is well known that a guest-host doped emitter system can significantly improve device performance in terms of EL efficiency and emissive color, as well as operational lifetime. In this work, a series of tetrakis(4-(9H-carbazol-9-yl)phenyl)silanes as blue host materials were synthesized and characterized by spectroscopy, cyclic voltammetry and x-ray measurements. These compounds have an ultra high energy band gap and also these compounds were thermally and morphologically stable blue host materials for OLED applications. Efficient blue phosphorescent OLEDs were obtained when employing TCPS as the host and FIrpic as the guest.
