Chem. Int. Ed. 59 (2020) 13468 –13472. A new Titanium Metal Organic Framework with visible-light responsive photocatalytic activity
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.
