| 摘要: 通过噻吩的氧化偶联反应，制得富含N、S杂原子的多孔有机聚合物PTPA。然后利用溶剂热法，合成了PTPA负载Cu-Cu2O的复合材料Cu-Cu2O/PTPA，并通过红外光谱(IR)、X射线衍射(XRD)、热重分析(TGA)、N2吸附-脱附、X射线光电子能谱(XPS)、扫描电镜(SEM)和高分辨透射电镜(HRTEM)等对其进行了全面表征。在30℃空气中的温和条件下，以2，2，6，6-四甲基哌啶氧化物(TEMPO)为助催化剂和N-甲基咪唑(NMI)为辅助配体，Cu-Cu2O/PTPA对苄醇、烯丙醇及杂环醇表现出良好的选择性催化氧化性能。这归因于该材料富含N、S杂原子，Cu-Cu2O/PTPA在催化苯甲醇氧化方面表现出优异的循环稳定性，重复使用9次后仍保持97%以上的产率。 | |

| Abstract: Porous organic polymer PTPA containing N, S heteroatoms has been prepared via oxidative coupling of thiophene. Then composite material Cu-Cu2O/PTPA was synthesized via solvothermal method and fully characterized by infrared spectroscopy (IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), N2 adsorption desorption, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTEM). Under the mild conditions of 30 ℃ and open air, Cu-Cu2O/PTPA showed good catalytic activity towards selective oxidation of benzyl, allyl, and heterocyclic alcohols employing 2,2,6,6-tetrameth- ylpiperidine 1-oxyl (TEMPO) as a co-catalyst and N-methylimidazole (NMI) as an auxiliary ligand. Due to the high content of N and S heteroatoms in the material, Cu-Cu2O/PTPA showed excellent cycling stability for oxidation of benzyl alcohol, and the yield of product remained above 97% after 9 runs. | |
