Efficient blue organic light-emitting diodes using N(2) ,N(2) ,N(11) ,N(11) ,5,6,7,8-octaphenyltriphenylene-2,11-diamine derivatives.
In this study, we have synthesized phenyl-substituted triphenylene derivatives, using the Diels-Alder reaction and the Buchwald-Hartwig reaction. To investigate electroluminescence properties of these materials, multilayer organic light-emitting diode (OLED) devices were fabricated with a structure of indium-tin-oxide (ITO) (180 nm)/4,4'-bis(N-(1-naphthyl)-N-phenylamino)biphenyl (NPB) (50 nm)/blue-emitting materials (1-3) (30 nm)/bathophenanthroline (Bphen) (35 nm)/lithium quinolate (Liq) (2 nm)/Al (100 nm). A device using N(2) ,N(2) ,N(11) ,N(11) ,5,6,7-heptaphenyltriphenylene-2,11-diamine (2) exhibited efficient blue emission with luminous, power, and external quantum efficiencies of 0.92 cd/A, 0.67 lm/W, and 1.17% at 20 mA/cm(2) , respectively. The Commission International de L'Éclairage coordinates of this device were (x = 0.15, y = 0.09) at 6.0 V. Copyright © 2015 John Wiley & Sons, Ltd.
