Abstract:	Bis(amino)distyrylbenzene derivatives N,N,N’,N’,-tetraphenyl-2,5-di(E)-styrylbenzene-1,4-diamin (DASB), N,N,N’,N’,-tetraphenyl-2,5-bis-(2-p-tolyl-vinyl)-benzene-1,4-diamin (DATB), 1,4-Dibromo-2,5-bis-[2-(4-methoxy-phenyl)-vinyl]-benzene (DAMB), 2,5-Bis-[2-(4-fluoro-phenyl)-vinyl]-N,N,N’,N’,-tetra-p-tolyl-benzene-1,4-diamine (DAFB), 2,5-Bis-[2-(4-methoxy-phenyl)-vinyl]-N,N,N’,N’-tetra-p-tolyl-1,4-diamine (DTMB) were conveniently synthesized from the corresponding 1,4-dibromo-distyrylbenzene derivatives and diarylamine in the presence of Pd(OAc)2, tri-tert-butylphosphine and potassium tert-butoxide in toluene. The physical properties of Bis(amino)distyrylbenzene derivatives were thoroughly investigated. Electroluminescent devices using DASB as the dopant emitters and host emitters were made. These devices all emit green light from the DASB emitter layer. Device A that consists of NPB (40 nm)/ DASB:Alq(5.3%, 30 nm)/ TPBI(50 nm)shows the highest performance. The device emits green light at 518 nm with CIE values of (0.26, 0.59) and shows a maximum external quantum efficiency of 1.93%, current efficiency of 6.58 cd/A, and brightness of 36795 cd/m2
