Electron Transfer in Donor–Acceptor Molecules of Substituted Naphtoquinones: 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 influenced the degree of formation of an internal charge transfer complex. Properties of the inter...

Description
Summary: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, andin situspectroelectrochemistry. Quantum chemical interpretation of experiments is given.
