Herein, a holistic strategy that transforms upconversion nanorods (UCNR) surface functionalization from an empirically treated outcome into an optically self\u2010reporting process via near\u2010infrared (NIR)\u2010mediated photoinduced electron\/energy transfer\u2010reversible addition\u2010fragmentation chain transfer (PET\u2010RAFT) polymerization is present. This three\u2010in\u2010one design, where the UCNR concurrently acts as a NIR\u2010harvesting antenna, polymerization substrate, and optical signaling unit, enables the precise, temporally controlled growth and monitoring of polymer shells with tunable thickness and grafting density. Critically, a linear correlation between the evolving polymer shell architecture and the upconversion luminescence intensity was unraveled, thereby turning the optical signal into a real\u2010time, nondestructive probe that reveals the invisible surface modification process. Building upon this self\u2010monitoring capability, the polymer brushes were further engineered to template the in situ growth of gold nanoparticles, establishing a cascaded energy transfer pathway for efficient photothermal conversion. Using the nanohybrids as a built\u2010in ratiometric fluorescent nanothermometer, the nanohybrid enables real\u2010time temperature feedback during NIR irradiation as precise nanothermometry. This work establishes a new paradigm for creating intelligent, self\u2010sensing nanoplatforms with profound implications for precision theranostics and adaptive photonic materials.<\/jats:p>","DOI":"10.1002\/anie.4453766","type":"journal-article","created":{"date-parts":[[2026,9,21]],"date-time":"2026-09-21T15:32:34Z","timestamp":1790004754000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Tailoring
