A supramolecular organic framework-type photocatalyst, named TM-SOF, is constructed by the self-assembly of cucurbit[8]uril and a tetra-arm monomer containing four N, N'-dimethyl 2,5-bis(4-pyridinium)thiazolo[5,4-d]thiazole (MPT) moieties. Benefiting from the multivalent assembly, a photocatalytically active supramolecular MPT dimer can be stably formed in TM-SOF. In addition, TM-SOF exhibits better stability against temperature, substrate, and light irradiation. As a result, TM-SOF shows a significantly improved performance for the photocatalytic aerobic oxidation of aryl boronic acids and thioethers. It is anticipated that this line of research will provide a facile approach for fabricating high-performance supramolecular photocatalysis systems.
一种名为TM-SOF的超分子有机框架型光催化剂，由葫芦[8]脲与含有四个N，N'-二甲基2,5-双（4-吡啶基）噻唑并[5,4-d]噻唑（MPT）部分的四臂单体自组装而成。得益于多价组装，在TM-SOF中可稳定形成具有光催化活性的超分子MPT二聚体。此外，TM-SOF在温度、底物和光照方面表现出更好的稳定性。因此，TM-SOF在芳基硼酸和硫醚的光催化需氧氧化方面表现出显著提高的性能。预计这一系列研究将为制备高性能超分子光催化体系提供一种简便方法。
