“…(1) Generally, large conjugated molecules have good light-absorbing efficiency, which can increase the rate of photoelectron generation, and provide a good hydrogen yield in the absence of photosensitizers. 8 Pyrene, a polycyclic aromatic compound containing four benzene rings, offers internal advantages for light absorption because of its large π-conjugated system. 9 (2) To date, some pyrene-based derivatives, such as TBP, 10 TPPH, 11 CP-CMP1-15, 12 TEBPY, TEPPY 13 and TBAPy, 14 have been confirmed to increase the rate of photoelectron generation and provide a good hydrogen yield.…”
