Electrochemical oxygen activation driven by enamine-keto push–pull interactions in triazole-based covalent organic polymers

Abstract

We have developed two triazole-based covalent organic polymers (COPs) with donor–acceptor motifs. The keto-enriched COP demonstrated exceptional oxygen activation via electrochemical stimuli, driven by strong push–pull interactions. In situ studies and DFT calculations confirmed the critical role of enamine carbon positive charges in enhancing performance, setting new benchmarks in COP design.
