In this study, a self\u2010assembled nanoreactor was developed to achieve localized supersaturation via the photooxidation of Cu\n                    <jats:sub>2<\/jats:sub>\n                    O nanoparticles under visible light irradiation. Unlike conventional methods, this strategy enables HKUST\u20101 crystallization at ambient temperature in water without external heating. By modulating the Cu\n                    <jats:sup>2+<\/jats:sup>\n                    release response and ligand accessibility, we propose a two\u2010step process in which a metastable supersaturation regime forms a shell, followed by a labile supersaturation regime that favors predominantly inward crystal growth at or near the core\u2010shell interface. Transport perturbations, shell characterization, and a limiting reaction\u2013diffusion analysis support this mechanistic interpretation, while local activities and the microscopic growth trajectory were not measured directly. X\u2010ray diffraction, Raman spectroscopy, and Brunauer\u2013Emmett\u2013Teller analyses confirmed the crystallinity and porosity of the resulting HKUST\u20101. By generating localized supersaturation while maintaining dilute bulk conditions, this approach provides a programmable reaction environment for nucleation and growth, thereby opening a mild aqueous route to advanced functional materials.\n
