Abstract

​We report the one step synthesis and characterization of a new and robust titanium‐based Metal Organic Framework, ACM‐1 . In this new structure, based on infinite Ti‐O chains and 4,4′,4″,4″′‐(pyrene‐1,3,6,8‐tetrayl) tetrabenzoic acid as a photosensitizer ligand, the combination of highly mobile photogenerated electrons and a strong hole localization at the organic linker results in large charge separation lifetimes. The suitable energies for band gap and CBM offer great potential for a wide range of photocatalytic reactions, from hydrogen evolution to the selective oxidation of organic substrates.
