Shaping Conducting Polymer Fibers by Means of Electrochemiluminescence Microscopy

ECL和双极电化学的结合已经导致了一个成功的战略，以丰富研究员关于双极电化学和一般双极电化学系统的科学知识。事实上，在发表在《分析化学》上的研究论文中，我们开发了一种简单直接的分析工具，通过成像适合触发发光反应的电位的位置来绘制建立在双极电极上的电极电位图。值得注意的是，当电化学电池的几何形状或驱动电极的位置改变时，这种分析工具允许量化双极电极上的电位变化，并且还允许监视其作为总施加电压的函数的演变。该方法的优势在于使用简单，因为它可以很容易地适应任何类型的双极电化学构型。在合作研究期间探索的另一种创新方法是使用不同类型的导电聚合物薄膜作为双极电极，以无线方式产生鲁米诺和过氧化氢的ECL发射。这项研究成果已作为2020年举行的第71届国际电化学学会(ISE)年会特刊的一部分发表在《电学学报》杂志上。

The combination of ECL and bipolar electrochemistry has resulted in a successful strategy to enrich the scientific knowledge of the research fellow regarding bipolar electrochemistry, and bipolar electrochemical systems in general. Indeed, in the research paper published in Analytical Chemistry, we have developed a simple and straightforward analytical tool to map the electrode potential established over a bipolar electrode, by imaging the location where the potential is suitable to trigger the luminescent reaction. Noteworthy, such analytical tool allows the quantification of the potential variation over the bipolar electrode when the geometry of the electrochemical cell or the positioning of the driving electrodes is varied, and also permits to monitor its evolution as a function of the total applied voltage. The strength of the method relies on the simplicity of use, because it can be readily adapted to any type of bipolar electrochemical configuration.Another innovative approach explored during the collaborative research has been the use of different type of conducting polymer films as bipolar electrodes to generate the ECL emission from luminol and hydrogen peroxide in a wireless manner. The results of this research have been published in Electrochimica Acta journal as a part of the Special Issue of the 71st Annual Meeting of the International Society of Electrochemistry (ISE) held in 2020.
