In this communication, a self-assembled supramolecular system consisting of phosphoric acid substituted perylene diimide (P-PMPDI) has been successfully developed for highly efficient photocatalytic hydrogen evolution. Compared with a carboxylic substituent perylene diimide (P-CMPDI), P-PMPDI showed a superior H2 evolution reaction rate of 11.7 mmol g-1 h-1 and a recorded apparent quantum yield (AQY) of 2.
