PENTACENEQUINONE DERIVATIVE AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a pentacenequinone derivative usable as a material for an organic electronic device such as a light emission element, a photoelectric transfer element and a semiconductor.;SOLUTION: A pentacene derivative is obtained by causing the pentacenequinone derivative represented by formula (I) to react with a Grignard reagent or an organolithium reagent, in which R¹ to R⁴ are H, an alkyl group or the like; and A¹ to A⁴ are H or an electron-withdrawing group such as an alkoxycarbonyl group, with at least one of A¹ to A⁴ being the electron-withdrawing group.;COPYRIGHT: (C)2014,JPO&INPIT
