4,4'-bis(4,6-diphenyl-1,3,5-triazin-2-yl)biphenyl

BTB (4,4'-bis(4,6-diphenyl-1,3,5-triazin-2-yl)biphenyl) is a white crystal that exhibits higher electron mobility[1]. It can be synthesized from 4,4-Biphenyldicarbonyl chloride, 1,2-dichlorobenzene, thionyl chloride, and aluminum chloride. It can be used as an electron transport material in organic light emitting devices.
