摘要：

We have designed and synthesized new dopant materials based on the styrylamine moiety, 4-[(1,2-diphenyl)-4'-(N,N-diphenyl-4-vinyl benzenamine)]biphenyl (4) and 4-[(1,2-dipbenyl)-4'-(N,N-diphenyl-4-vinylbenzenamine)]terphenyl (8). Blue OLEDs were obtained from new styrylamine dopant materials and compared with those of blue dopant bis[4-(di-p-N,N-diphenylamino)styryl]stilbene (DSA-Ph) and diphenyl[4-(2-terphenyl vinyl)pherlyl]lamine (R-BD). The ITO/DNTPD/NPB/MADN:dopant/Alq(3)/Al-LiF device obtained from 4 shows blue EL spectrum at 469 nm and high efficiency 3.02 cd/A at 7 V 8 also shows blue EL spectrum around lambda(max) = 468 nm, efficiency of 3.51 cd/A and a current density of 25.94 mA/cm(2) (855.7 cd/m(2)) at 7 V.
