In the photoinduced hydrogen evolution with a four-component (electron donor-photosensitizerelectron carrier-catalyst) system, the charge separation step between the photoexcited sensitizer and electron carrier is one of the most important processes. As methylviologen (electron carrier) is complexed with [Zn-TPPS3]3- photosensitizer and the comp lex is inactive as a photosensitizer, the effective concentration of the photosensitizer decreases. When various bipyridinium compounds are used as electron carriers, some bipyridinum compounds are complexed with [Zn-TPPS3]3- to a smaller extent and the higher photoinduced hydrogen evolution rates are observed.
