Boosting Electrochemiluminescence of Carbon Nitrides via Molecular Capacitor-Mediated Spatiotemporal Electron Coordination.

ABSTRACT: Carbon nitride (CN) enables non-toxicity, low cost, high quantum efficiency, and tunable spectrum. Nevertheless, there co-exists a timescale mismatch among kinetic steps of electrochemiluminescence (ECL) and a spatial competition of electrons between radiative recombination and interfacial redox reactions. Herein, a spatiotemporal coordination strategy is reported to enhance Φ_ECL of CN by molecular capacitor functionalization. Mechanism studies show the capacitor, consisting of N-vacancies and -C≡N terminal groups, dynamically regulates electron capture and accumulation. Interestingly, the spatial confinement of accumulated electrons in molecular capacitors effectively enhances the radiative recombination probability. Meanwhile, the accumulated electrons construct a new pathway
