The coupling reaction of 4‐nitrothiophenol to 4,4′‐dimercaptoazobenzene was investigated by surface enhancement Raman scattering method. The reaction was found to be controlled by the compatibility of organic alkalis and silver nanoparticles. The effect of hot electron–hole pairs on the reaction was evaluated. Furthermore, the mechanism of organic alkalis affecting hot electron–hole pairs to achieve regulation of the coupling reaction of 4‐nitrothiophenol to 4,4′‐dimercaptoazobenzene was studied. A comprehensive analysis of the different surface enhancement Raman scattering signals collected was conducted. The forward‐looking view of capturing holes through the hydrolysis of organic alkalis to ensure the integrity of the substrate was also presented.
