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-Cu_(2)O的复合材料Cu-Cu_(2)O/PTPA,并通过红外光谱(IR)、X射线衍射(XRD)、热重分析(TGA)、N_(2)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-Cu_(2)O/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-Cu_(2)O/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。Porous organic polymer PTPA containing N,S heteroatoms has been prepared via oxidative coupling of thiophene.Then composite material Cu-Cu_(2)O/PTPA was synthesized via solvothermal method and fully characterized by infrared spectroscopy(IR),X-ray diffraction(XRD),thermogravimetric analysis(TGA),N_(2) 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-Cu_(2)O/PTPA showed good catalytic activity towards selective oxidation of benzyl,allyl,and heterocyclic alcohols employing 2,2,6,6-tetramethylpiperidine 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-Cu_(2)O/PTPA showed excellent cycling stability for oxidation of benzyl alcohol,and the yield of product remained above 97%after 9 runs.
