Coadsorption self-assembled monolayers of trithiocyanuric acid and 1,3,5-benzenetrithiol on an evaporated silver film

► We clarified the adsorption structure of 1,3,5-benzentrithiol (BTT) on silver film. ► The adsorption model of BTT was verified by both IRAS method and theoretical calculations. ► We found that an adsorption of trithiocyanuric acid was prohibited by BTT in coadsorption system.
