P-165: Efficient RGBW OLEDs based on 4, 4′-bis (1, 2, 2-triphenylvinyl) biphenyl

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.
