반응 단계

A mixture of 5 g (15.5 mmol) of perylene-3,4-dicarboxylic anhydride (prepared in accordance with Liebigs Ann. 1995, 1229–1244), 2.44 g (17 mmol) of n-nonylamine and 75 ml of N-methylpyrrolidone (NMP) was heated at 175° C. under nitrogen for 1.5 h. After cooling to room temperature, the resulting precipitate was filtered off, washed with methanol and dried under reduced pressure at 80° C. This gave 5.5 g (79%) of the desired product in the form of dark red crystals having a melting point of 201° C.
