Abstract
The interaction mechanism of 2,5-dimercapto-1,3,4-thiadiazole (DMTD) on cop per surface was studied by surface-enhanced Raman scattering (SERS), infrar ed (IR) and X-ray photoelectron spectroscopy (XPS) techniques. The SERS spe ctra were obtained. We found that DMTD bound with the copper via its two-ex cocyclic mercapto groups. The monosulphide salt was formed. At the same tim e, DMTD coordinated with the Cu+ ion through the excocyclic mercapto groups and polymerized via the Cu+ ion into a one-dimensional polymer chain on th e copper surface.
