The light–matter interaction is the crucial tool for the efficient light energy usage. Electrochemical potential control method can tune the coupling strength between the molecules and the light field. In this study, electrochemical surface‐enhanced Raman scattering measurements have been carried out to clarify the detailed molecular behavior in the strong coupling regime. The Raman and fluorescence intensities from dye molecules in the strong coupling regime provided us the information about the change in the distance between the molecules and the metal surface in angstrom level. The detailed investigation of spectra revealed the origin for the potential dependence on the coupling strength. The present insight obtained in the current study would be valuable to understand the electrochemically controlled molecule–light interaction for photochemistry research.

表面增强拉曼散射探针，用于在电化学电势控制下将分子与局部表面等离激元牢固偶联

光与物质的相互作用是有效利用光能的关键工具。电化学势控制方法可以调节分子与光场之间的耦合强度。在这项研究中，已经进行了电化学表面增强拉曼散射测量，以阐明强耦合状态下的详细分子行为。染料分子在强耦合状态下的拉曼光谱和荧光强度为我们提供了有关分子与金属表面之间距离的变化（埃级）的信息。光谱的详细研究揭示了电位对耦合强度的依赖性。
