Abstract
The title electron donors 1 as well as their conjugate bases 2− undergo reversible two-stage one-electron oxidation. ESR analysis indicated the important contribution of zwitterionic structure for radicals 2. Bis(zwitterionic) but not quinoid structure was suggested for p-4, generated from the twin-type dianionic donor p-42− with a p-phenylene spacer.
