Abstract: 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 influenced the degree of formation of an internal charge transfer complex. Properties of the internal charge transfer interactions were investigated by voltammetry, spectroscopy, and in situ spectroelectrochemistry. Quantum chemical interpretation of experiments is given.
