In parallel, tetrazoles have become powerful \u201cclick\u201d reagents for light\u2010activated, bioorthogonal ligations, yet remain unexplored in reagents with delayed emission lifetimes. Here we report the design and synthesis of TADF\u2010active tetrazole luminophores with photochemical reactivity for the rapid functionalization of nanoparticles and surfaces. The combination of electron\u2010rich phenoxazine donors with electron\u2010deficient tetrazole acceptors yields luminophores with bright emission and tunable TADF lifetimes, governed by the 1,3\u2010dipolar cycloaddition partner. Cycloaddition with alkene dipolarophiles affords saturated dihydropyrazoles that undergo photoinduced aerobic aromatization to generate pyrazole products exhibiting pronounced turn\u2010on TADF behavior. Leveraging their charge\u2010transfer character, we also demonstrate a gold surface modified with TADF luminophores, wherein we propose the first example of reversible visible light\u2010induced surface adsorption. Furthermore, we demonstrate the surface functionalization of organic nanoparticles using TADF\u2010active materials. This work introduces a class of functional materials that combine photochemical reactivity with TADF properties, introducing a light\u2010driven platform for surface functionalization using TADF materials.<\/jats:p>","DOI":"10.1002\/anie.9410589","type":"journal-article","created":{"date-parts":[[2026,8,29]],"date-time":"2026-08-29T05:42:41Z","timestamp":1787982161000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["TADF\u2010Active
