Abstract
The one-step synthesis and characterization of a new and robust titanium-based metal-organic framework, ACM-1, is reported. In this structure, which is 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 conduction band minimum (CBM) offer great potential for a wide range of photocatalytic reactions, from hydrogen evolution to the selective oxidation of organic substrates.
