Abstract Controlled surface functionalization of electrode materials is an important technique in various fields such as analytical chemistry, molecular electronics, and molecular recognition in biological systems. In this work, we report the control decoration of boron-doped diamond (BDD) electrodes by electrochemically driven copper(I)-catalyzed Huisgen 1,3-dipolar cycloaddition of alkyne and azide (e−CLICK) in which the catalyst is produced by electroreduction of copper(II) species. As the e−CLICK strategy enabled to tune the produced amount of the copper(I) catalyst electrochemically, the alkyne-terminated BDD electrodes were decorated with azide-terminated ferrocene in a controlled manner.

通过电化学点击反应（e-CLICK）控制掺硼金刚石电极的装饰

摘要 电极材料的受控表面功能化是分析化学、分子电子学和生物系统中的分子识别等各个领域的重要技术。在这项工作中，我们报告了通过电化学驱动的铜 (I) 催化的 Huisgen 1,3-炔烃和叠氮化物的偶极环加成 (e-CLICK) 控制掺硼金刚石 (BDD) 电极的装饰，其中催化剂由铜 (II) 物种的电还原。由于 e-CLICK 策略能够以电化学方式调节铜（I）催化剂的产生量，因此炔烃封端的 BDD 电极以可控的方式用叠氮化物封端的二茂铁进行装饰。
