However, their development has been impeded by the persistent trade\u2010off between degradability and mechanical strength, as well as the lack of effective polymerization strategies that can be used under mild conditions. Herein, we report a polyoxometalate (POM)\u2010mediated \u201cone\u2010stone\u2010three\u2010birds\u201d strategy, in which rapid ring\u2010opening polymerization (ROP) of TA is synchronously coupled with noncovalent crosslinking under mild ambient conditions. Combined experimental and theoretical investigations reveal that POM nanoclusters act as multifunctional \u201cstones\u201d: oxidizing TA to generate cationic radical species that initiate ROP, engaging in strong electrostatic interactions with the sulfonium termini of the resulting PTA chains to form robust polymer networks with high adhesion strength (&gt;11\u00a0MPa), and imparting a redox\u2010responsive colorimetric signal. This synergistic integration of mechanical reinforcement and chromic response provides a new strategy for designing adhesives with coupled structural integrity and optical feedback, which enables in situ visual indication of material changes during leakage of oxidizing species in confined environments.<\/jats:p>","DOI":"10.1002\/anie.7949913","type":"journal-article","created":{"date-parts":[[2026,8,15]],"date-time":"2026-08-15T06:14:46Z","timestamp":1786774486000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Polyoxometalates\u2010Driven
