A Proton-Responsive Backbone Relay for Selective Two-Electron Oxygen Reduction to H2O2
Efficient photocatalytic H2O2 production in organic polymers requires the coordinated regulation of charge separation, O2 activation, and proton delivery, yet these processes are often optimized independently. Here, we report a postsynthetic thiol–yne editing strategy that converts a passive alkynyl bridge in a donor...
