Surface plasmon resonances enhanced click chemistry through synergistic photothermal and hot electron effects

Abstract

Surface plasmon resonances of Au nanoparticles were shown to enhance a copper catalyzed 1,3-dipolar azide–alkyne cycloaddition reaction, through synergistic photothermal and hot electron effects. By improving hot electron utilization with Au–CuO nanohybrids, efficient azide–alkyne cycloaddition has been realized under ambient conditions without using conventional heating and a chemical reducing agent.
