Anthracalimide dioxime was synthesized for used as acceptor materials of organic solar cell.Compound 1 was acquired by a cyclization reaction of aceanthracenequinone with sulfamide.Dry HCl was employed as a catalyst.Compound 1 was added into a solution of diethylene glycol and diethyl ether.The solution was refluxed to give compound 2,a yellow powder.A solution of compound 2,hydroxylamine hydrochloride,and sodium acetate in ethanol-water was refluxed to get a yellow solid.The crude product was recrystallized from ethanol to give anthracalimide dioxime,yellow crystal.
