With reference to the following scheme, perinaphthene and zinc powder were added to pyridine (I in the following synthesis scheme), 50 ml of 80% acetic acid was added dropwise thereto with stirring under reflux in nitrogen flow over five hours, the resulting precipitate (II in the following synthesis scheme I) was filtrated, was dehydrated and sublimated using a vacuum sublimation apparatus and thereby yielded unsubstituted peropyrene (III in the following synthesis scheme).
