摘要: Abstract Photoelectric measurements were performed on powder samples of ion-pair complexes mono- and dianionic nickel zinc dithiolenes with redox-active cations like 2,2′-and 4,4′-bipyridinium or simple tetraalkylammonium derivatives. From the dependence photoconductivity temperature, applied electric field wavelength exciting light it is suggested that charge generation dominated by optical transfer (IPCT) from anion to cation. Accordingly, low energy maxima appear in region IPCT bands are shifted linearly higher when, for a given donor [ZnL 2 ] 2− , reduction potential acceptor becomes more negative.
