4,4'-Bis[4-(di-p-tolylamino)styryl]biphenyl

DPAVBi, 4,4′ -Bis[4-(di-p-tolylamino)styryl]biphenyl is widely used as a sky-blue fluorescent emitter in OLED devices. It is also used as a blue dopant for white TADF-OLED devices.

It may be used as a dopant for fluorescent host material, 6-anthracene-9-yl-2,3-di-p-tolyl benzo[b]thiophene (ATB) for the fabrication of organic light emitting diodes (OLEDs.) It may also be used as a dopant for white organic light emitting diodes.

DPAVBi is a blue fluorescent dopant material. It exhibits a maximum electroluminescent efficiency of 8.6 cd/A 7.4 cd/A at 1000 cd/m² and 10.4 lm/W at 2.6 V 6.4 lm/W at 1000 cd/m².
