Electrochemical reduction and oxidation potentials and standard heterogeneous electron transfer rate constants are reported for 2,3-diamino-1,4-naphthoquinone and two of its N-alkylated derivatives in acetonitrile. For two of the compounds, spectroelectrochemistry was used to obtain the absorption spectra of the radical cation and the radical anion. The compounds can be viewed as captodative biradicaloids and as such are of interest for photophysical studies of singlet fission.
