X-ray diffraction analysis. The electrochemical behavior of copper(II)-Schiff base complex containing pyrrol groups has been investigated in DMF and acetonitrile solutions using cyclic voltammetry. Thus, conducting polymeric films of polypyrrole were obtained on the surfaces of glassy carbon and ITO electrodes using copper(II) complex as monomer. The modified electrodes were electrochemically and morphologically
摘要 在乙酸铜一水合物存在下,以 6-[3'-(N-吡咯)丙氧基]-2-羟基苯乙酮和二氨基乙烷为原料制备了含有 N2O2 供体原子的新型铜 (II) 配合物 Cu(II)-L。通过光谱方法,如FT-IR、UV-vis、质谱、元素分析和循环伏安法对其进行表征。Cu(II)-L 的分子结构也已通过 X 射线衍射分析得到证实。使用循环伏安法研究了含有吡咯基团的铜 (II)-席夫碱络合物在 DMF 和乙腈溶液中的电化学行为。因此,使用铜(II)配合物作为单体,在玻璃碳和 ITO 电极的表面上获得了聚吡咯的导电聚合物薄膜。对修饰电极进行了电化学和形态学表征,并研究了它们在异相中的电催化性能。AFM 研究表明,ITO 电极上聚吡咯 (PPy) 薄膜的形态取决于循环扫描的次数。这种配合物的电催化性能似乎比任何其他类型的醇(如甲醇、乙醇和苯甲醇)对异丙醇的电氧化更有效。还检查了二氧化碳的电还原。这种配合物
