A Novel Blue Light Emitting Material Prepared from 2-(o-Hydroxyphenyl)benzoxazole

Abstract

Abstract A new organozinc compound, zinc bis-2-(o-hydroxyphenyl)benzoxazolate, was prepared from 2-(o-hydroxyphenyl)benzoxazole and electroluminescent properties of the compound was investigated. An electroluminescent device was composed of glass substrate/indium-tin-oxide/hole transporting layer/zinc benzoxazolate/Al thin films. The electroluminescence of blue light was observed with the electric field of over 90 MV/m.
