Procedure

A suspension of pentacene (287 mg, 1 mmole) and maleimide (1 mmole) in 4 mL of dichlorobenzene is heated to 160° C. for 4 hours. The mixture is cooled to room temperature and the precipitate is filtered, washed with toluene and dried. Recrystallization from dichlorobenzene affords pure samples of pentacene-maleimide adduct as white needles.
