Abstract We report a newly synthesized wide band‐gap material 4, 4′‐bis (1, 2, 2‐triphenylvinyl) biphenyl (BTPE), which can serve as blue emitter directly or as host for fluorescent green and red dyes. By employing BTPE as host and/or emitter, efficient red, green, blue and white OLEDs show a maximum current efficiency of 5 cd/A, 18 cd/A, 7.1 cd/A and 7 cd/A, respectively.
