To construct photocatalytically active MOFs, various strategies have recently been developed. We synthesized and characterized a new metal–organic framework (MOF-253-Pt) material through immobilizing platinum complex in 2,2′-bipyridine-based microporous MOF (MOF-253) using post-synthesis modification strategy. The functionalized MOF-253-Pt serves both as photosensitizer photocatalyst for hydrogen evolution under visible-light irradiation. photocatalytic activity of is approximately five times higher than that the corresponding complex. presence short Pt⋯Pt interactions was revealed with extended X-ray absorption fine structure (EXAFS) spectroscopy low temperature luminescence. These play an important role improving resulting MOF.
