The synthesis of pyrroles functionalized by complexing groups such as acetylacetone, dibenzoylmethane or carboxylic acids is described, as well as their electrooxidation into functionalized polypyrroles. We have studied the behavior of poly(functionalized pyrrole) films in the presence of Li+, Ni2+ and Co2+ cations by cyclic voltammetry (CV) and infrared (IR) spectroscopy. The electrochemical response under various conditions differs with the nature of the complexing group. We have also demonstrated the possibility to electrochemically generate copolymers with pyrrole and each functionalized pyrrole. The proportion of functional groups in the copolymers was estimated by following
the peak potential dependence in cyclic voltammetry and was confirmed by IR spectroscopy.
文中描述了通过乙酰丙酮、二苯甲酰甲烷或羧酸等配位基团功能化的吡咯的合成方法,以及它们电氧化成为功能化聚吡咯的过程。我们通过循环伏安法(CV)和红外(IR)光谱研究了聚(功能化吡咯)薄膜在Li+、Ni2+和Co2+阳离子存在下的行为。在不同条件下,电化学响应随配位基团性质的不同而有所差异。我们还展示了通过电化学方法生成吡咯和每种功能化吡咯的共聚物的可能性。通过跟踪循环伏安法中峰电位的依赖性来估计共聚物中功能基团的比例,并通过红外光谱确认。
