Manufacture and evaluation of Green Organic Light Emitting Device (Phosphorescent Host)

[0102]An organic electroluminescent device was fabricated according to a conventional method using a compound obtained through synthesis as a host material of an emitting layer. First, on an ITO layer(anode) formed on a glass substrate, N1-(naphthalen-2-yl)-N4,N4-bis(4-(naphthalen-2-yl(phenyl)amino)phenyl)-N1-phenyl benzene-1,4-diamine(hereinafter will be abbreviated as 2-TNATA) was vacuum-deposited to form a hole injection layer with a thickness of 60 nm, and subsequently, on this film, 4,4-bis [N-(1-naphthyl)-N-phenylaminolbiphenyl (hereinafter will be abbreviated as NPB) as a hole transporting compound was vacuum-deposited to form a hole transport layer with a thickness of 60 nm. On the hole transport layer, the inventive compound or comparative compound A [CBP(4,4′-N,N-dicarbazole-biphenyl)] or comparative compound B or comparative compound C were used as a host, and as a dopant, an emitting l...
