Notes:
Azoles such as benzotriazole and benzimidazole are used as corrosion inhibitors, particularly for copper. The purpose of this work is to further illuminate the bonding and film growth for benzimidazole-like structures. The interaction of imidazole, benzimidazole, 2-methylbenz-imidazole and benzotriazole with copper surfaces is studied with a quartz crystal oscillator microbalance and with X-ray photoelectron spectroscopy. The copper surface is etched by imidazole in water and in CH3OH and by benzimidazole in CH3OH. A very thin film, probably a monolayer or less, is left behind after etching. Thicker films, 500 to 1000 AÅ, are formed by benzimidazole in water and by 2-methylbenzimidazole in both water and CH3OH. Mechanisms of bonding and film formation for the thin and the thick films are discussed.
