Emitting materials based on phenylanthracene-substituted naphthalene derivatives for organic light-emitting diodes

초록

This study reports the emitting materials based on phenylanthracene-substituted naphthalene derivatives to achieve efficient electroluminescent properties for OLED applications. An OLED device using 4,4'-bis(10-phenylanthracen-9-yl)-1,1'-binaphthalene exhibited the blue emission with the CIE coordinates of (0.19, 0.16) and efficient electroluminescent properties with the luminance, power and external quantum efficiency of 1.70 cd/A, 0.79 Im/W and 1.26% at 20 mA/cm(2), respectively. Also, the other device using 1, 4-bis(10-phenylanthracene-9-yl)naphthalene exhibited white emission with the CIE coordinates of (0.34, 0.43) at 7V, respectively. This device exhibits the luminance, power and external quantum efficiency of 2.22 cd/A, 1.13 Im/W and 0.86% at 20 mA/cm(2), respectively. (C) 2015 Elsevier B.V. All rights reserved.
