Search for a one-electron reduction of the cation radical of an "extended viologen," p-phenylene-bis-4,4'(1-aryl-2,6-diphenylpyridinium)

Abstract

Electrochemical one-electron reduction of the "extended viologen" dication to yield the red cation radical, which readily produces a dark-blue dimer. The second reduction step corresponds to the reduction of dimer.
