Abstract
Photo-oxidation and photoreduction of bis(dithiobenzil)nickels have been investigated. The quantum yields for photo-oxidation of anionic bis(dithiobenzil)nickels by u.v. irradiation (313 nm) were in the range 0.07–0.14 in dichloromethane, and this photo-oxidation on poly(methylmethacrylate) was also observed. Some of the neutral bis(dithiobenzil)nickels in acetonitrile/benzene mixture were photoreduced in the presence of methylene blue as a sensitiser by irradiation in visible light (>390 nm), and a significant substituent effect was observed.
