开发并研究了一种电化学形式的有机催化原子转移自由基聚合（O-ATRP）。受电化学介导的原子转移自由基聚合（eattp）的启发，恒电位电解用于操纵O-ATRP中催化剂的氧化还原状态，以了解是否可以增强O-ATRP中的失活以改善聚合控制。在此过程中，研究了几种可能的副反应，并对电化学装置进行了优化，以减少对电极上的副反应。然后，在不同的应用电位、不同的辐照条件和两种光氧化还原催化剂下，研究了这种电化学修饰的O-ATRP方法（eO-ATRP），以了解电解对聚合控制的影响。最后，虽然电解法成功地用于改善O-ATRP的聚合控制，但也发现了一些额外的挑战。提出了指导这一领域今后工作的几个关键问题。
An electrochemical variant of organocatalyzed atom transfer radical polymerization (O-ATRP) is developed and investigated. Inspired by electrochemically mediated atom transfer radical polymerization (eATRP), potentiostatic electrolysis is used to manipulate the catalyst’s redox states in O-ATRP to understand whether deactivation in O-ATRP can be enhanced to improve polymerization control. During the course of this work, several possible side reactions are investigated, and the electrochemical apparatus is optimized to reduce side reactions at the counter electrode. This electrochemically modified O-ATRP method (eO-ATRP) is then studied at different applied potentials, under different irradiation conditions, and with two photoredox catalysts to understand the impact of electrolysis on polymerization control. Ultimately, although electrolysis was successfully used to improve polymerization control in O-ATRP, some additional challenges have been identified. Several key questions are postulated to guide future work in this area.
