چکیده انگلیسی
Three blue materials based on diphenylamino dibenzo[g,p]chrysene were designed and synthesized via Buchwald-Hartwig amination. To characterize their electroluminescent properties, multilayered organic light emitting diodes (OLEDs) were fabricated with the following device structure: indium tin oxide (ITO) (180Â nm)/4,4â²,4â³-tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA) (40Â nm)/N,Nâ²-diphenyl-N,Nâ²-(1-napthyl)-(1,1â²-phenyl)-4,4â²-diamine (NPB) (10Â nm)/2-methyl-9,10-di(naphthalen-3-yl)anthracene (mADN): 3 or 7% blue dopants (20Â nm)/tris-(8-hydroxyquinoline)aluminum (Alq3) (30Â nm)/lithium quinolate (Liq) (2Â nm)/Al (100Â nm). All the devices showed blue emission with high electroluminescent efficiencies. Particularly, a device using 2-methyl-9,10-di(naphthalen-3-yl)anthracene as the host material and 3,6-di[4â²-(1-di(tert-butyl))phenyl]-11,14-bis(diphenylamino) dibenzo[g,p]chrysene (2) as the dopant material at 3% doping exhibited highly efficient blue emission with an external quantum efficiency of 4.72% at 20Â mA/cm2.
