Abstract

Among three noble-metal-free molecular devices (1–3) containing a porphyrin photosensitizer and a cobaloxime catalyst, the one with a zinc porphyrin unit displayed apparently higher efficiency for photoinduced H₂ production than complex 2 with a magnesium porphyrin and 3 with a free-base porphyrin, possibly due to the formation of a TEA⋯ZnPor–Co triad in solution.
