摘要
We report the photo-(PL) and electroluminescence (EL) properties of new conjugated compounds based on diphenyl benzeneamine moiety, 4,4'-[1,4-phenylenedi-(1E)-2,1-ethenediyl]bis[N,N-diphenyl-benzenamine](PEDB) and 4,4'-([1,1'-biphenyl]-4,4'-diyldi-2,1-ethenediyl)bis[N,N-diphenyl-benzenamine](BPEDB), as emitting materials and dopant materials. The ITO/m-MTDATA/NPB/DPVBi+ BPEDB(1%)/Alq(3)/LiF/Al device shows blue EL spectrum at 458 nm and high efficiency(5.3 cd/A). PEDB as dopant shows also blue EL spectrum around lambdamax=463 nm and 4.1 cd/A high efficiency in ITO/m-MTDATA/NPB/DPVBi+ PEDB(1%)/Alq(3)/LiF/Al device. (C) 2003 Elsevier B.V. All rights reserved.
