Abstract

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%) /Alq3/LiF/Al device shows blue EL spectrum at 458nm and high efficiency(5.3 cd/A). PEDB as dopant shows also blue EL spectrum around ${\lambda}$ max=463nm and 4.1 cd/A high efficiency in ITO/m-MTDATA/NPB/DPVBi + PEDB(1%)/Alq3/LiF/Al device.
