Blue-light-driven aerobic oxidation via a superoxide radical-generating zinc( ii )-organic framework photocatalyst
Abstract
). Structural analysis confirms a crystalline 1D chained structure with hierarchical porosity. Mechanistic investigations reveal a synergistic effect between anthracene-mediated light absorption and zinc(II)-mediated redox reactions. Under blue-light irradiation, Zn-1D exhibits outstanding catalytic performance in aerobic oxidation reactions, such as thioether oxidation. The microporous channels of the framework stabilize reactive intermediates, preventing overoxidation. Moreover, its excellent chemical and thermal stability allows for five consecutive recycling cycles without loss of activity. This work provides a new model for noble-metal-free photocatalysis by utilizing MOF-confined dual-function sites for blue-light-driven organic transformations, thus promoting the development of sustainable synthetic methods.
