Absorption in the ultraviolet of copper-complex compounds in hydrocarbons

Summary

Absorption spectroscopy in the near ultraviolet was used to explain high electrical conductivities obtainable in aromatic hydrocarbons on addition of copper chloride to illuminated solutions of suitable substrates, such as diketones and carboxylic acids. In particular, the inhibition of these high conductivities in the presence of hydroxyl compounds (water, ethanol) or by aliphatic solvents was investigated. Marked changes in the absorption curves of CuCl2 substantiate the assumption that the ionic species are the result of complex formation between Cu++ ions and photochemical products of the substrate. Characteristic shifts in the absorption curves when compared with corresponding uninhibited solutions were obtained in the presence of inhibitors or an aliphatic solvent. These shifts indicate a change in the structure of the copper-complex, brought about by the inhibitor.
