    • Although the cation–radical of Awas stable in solution (as established by the reversible CV), it was not sufficiently persistent to allow isolation of the cation–radical salt A+ SbCl6−. Thus B++ and not A+ was used to establish the geometrical (bond-length) change in Dupon 1-electron oxidation to the cation–radical D+ with q = 1

    • All the aromatic donors in Classes I–III show chemically reversible cyclic voltammograms with anodic/cathodic peak current ratio in the value: 0.9, 1.1. The quantitative electrode behavior relative to the electrochemical reversibility of these interesting redox couples will be addressed in a later study
