虽然导电聚杂芳族化合物已被广泛研究，但含有异羟肟酸基团的那些还没有被研究。本工作从一系列N-取代酯基出发，合成了N-（羟肟酸）吡咯和N-（羟肟酸）咔唑衍生物。然后在氧化剂如过硫酸铵和高氯酸铁（III）的存在下使所获得的化合物化学聚合。这些聚合物的电导率通过四种探针方法测量。化合物N-（2-乙烷-羧异羟肟酸）吡咯（VI）、9-（羧异羟肟酸）咔唑（VII）和9-（2-乙烷羧异羟肟酸）咔唑（XII）通过循环伏安法在6 × 10− 3 M单体、0.1M高氯酸四丁基铵、20 ml乙腈、Pt盘工作电极和SCE作为参比电极的条件下成功地电聚合。这些化合物与某些金属形成有色配合物。
Although conducting polyheteroaromatics have been widely investigated, those containing hydroxamic acid groups have not been studied. In this work we have synthesized various N-(carbohydroxamic acid)pyrrole and N-(carbohydroxamic acid)carbazole derivatives from a series of N-substituted ester groups. The compounds obtained were then chemically polymerized in the presence of oxidants such as ammonium persulphate, and Iron (III) perchlorate. The conductivity of these polymers was measured by four probe methods. The compounds N-(2-ethane-carbohydroxamic acid)pyrrole (VI), 9-(carbohydroxamic acid)carbazole (VII), and 9-(2-ethanecarbohydroxamic acid)carbazole (XII) were successfully electropolymerized by a cyclic voltametry method under 6 × 10−3M of monomer, 0.1 M tetrabutylammonium perchlorate, 20 ml acetonitrile, Pt disk working electrode, and SCE as a reference electrode condition. These compounds gave coloured complexes with certain metals.
