When Aromaticity Meets Silver: π–Ag₆Charge Transfer as a Molecular Trigger for SERS
This study establishes a quantitative correlation between adsorption-induced aromaticity modulation and Surface-Enhanced Raman Scattering (SERS) intensity in π-systems interacting with silver clusters, demonstrating that enhanced π-electron delocalization and charge transfer serve as key mechanistic drivers for chemical SERS activity.
