ELECTRON-TRANSFER IN DONOR-ACCEPTOR MOLECULES OF SUBSTITUTED NAPHTHOQUINONES - SPECTRAL AND REDOX PROPERTIES OF INTERNAL CHARGE-TRANSFER COMPLEXES

The investigated compounds were substituted naphtoquinones containing aniline moiety separated from the quinoid system by a methylene bridge . The nature of substituents on both donor and acceptor parts influenc ed the degree of formation of an internal charge transfer complex. Pro perties of the internal charge transfer interactions were investigated by voltammetry, spectroscopy, and in situ spectroelectrochemistry. Qu antum chemical interpretation of experiments is given.
