The self-assembled monolayer (SAMs) of 2-(1-tosyl-1H-1,2,3-triazol-4-yl) propan-2-ol (TTP) was in-situ assembled on copper surface via click chemistry reaction between 2, 2-dimethylethynyl carbinol (MBY) and tosyl azide (TA). The electrochemical results indicate that the click-assembled TTP film can strongly suppress the corrosion reaction of copper in 3 wt.% NaCl and its protection efficiency is 93.6%. Polarization curves show that TTP SAMs is an anodic passivation type inhibitor. The adsorption of TTP molecules on Cu2O (0 0 1) surface is in the flat orientation of the nearby triazole ring and O atoms.
