Cyclic voltammetry (CV) was used to investigate the electrochemical behavior of N-methylimidazole derivatives. The eletroreduction process was monitored by in situ UV spectroscopy, a few new absorbance were observed with increase of polarization potential, and the mechanism of eletroreduction for the N-methylimidazole derivatives was discussed.

Key words: N-methylimidazole derivative, UV spectroscopy, cyclic voltammetry, in situ UV spectroelectrochemistry
