important means of green catalytic organic synthesis. However, traditional photosensitizers (organic dyes or precious transition metal complexes, for instance) have limited applications due to their inherent toxicity and non-reusability. A β-ketoenamine-linked covalent organic framework (TAPT-TP-COF), as a heterogeneous photocatalyst, was synthesized by solvothermal reaction and characterized by FT-IR, XPS
可见光催化已逐渐成为绿色催化有机合成的重要手段。然而,传统的光敏剂(例如有机染料或贵过渡金属络合物)由于其固有的毒性和不可重复使用性而限制了应用。通过溶剂热反应合成了一种β-酮烯胺连接的共价有机骨架(TAPT-TP-COF)作为多相光催化剂,并通过 FT-IR、XPS、SEM、TEM、XRD、BET 和光学性能测试对其进行了表征。TAPT-TP-COF对N分子内环化反应合成2-芳基苯并噻唑表现出良好的光催化活性、显着的底物范围和可回收性能-芳基苯硫代酰胺。该研究为光催化领域的环化反应提供了新的解决方案。
