In this study, we investigate whether plasmonic nanostructures can serve as universal energy donors to activate redox-inert gold(I) complexes relevant to photo-driven catalysis. Using a molecular mediator, we demonstrate that localized energy from gold nanoparticles can be transferred through a two-step Dexter-type mechanism to generate the reactive first triplet metal-to-ligand charge-transfer state of the gold complex, even under non-resonant excitation. Spectroscopic analyses confirm the formation and lifetime of this excited state and reveal emission-based signatures of successful energy transfer. These results establish a mechanistic foundation for plasmon-enabled activation and open new possibilities for designing catalytic systems where precise energetic control and compatibility with a broad range of substrates are critical.
