Porter, William W. III published the artcileIsolation and Characterization of Phenyl Viologen as a Radical Cation and Neutral Molecule, HPLC of Formula: 47369-00-6, the publication is Journal of Organic Chemistry (2005), 70(13), 5028-5035, database is CAplus and MEDLINE.
The chem. synthesis, isolation, and characterization of Ph viologen (PV) as a dication, radical cation, and neutral species are described. Single-crystal X-ray diffraction of PV2+2Cl–·2H2O and PVâ?PF6–·pyridine reveals the expected differences in bond lengths and also a structural change from two coplanar central rings in PVâ? to a twist of 36° between the two central rings in PV2+. The Ph viologen radical cation exhibits behavior characteristic of many radical cations, including weak Ï-dimerization in the solid state and reversible Ï-dimerization in solution Elec. conductivity measurements of neutral Ph viologen, the first such measurements of a neutral viologen, reveal that it is a significantly better conductor than the radical cation. Differences in geometric relaxation during charge transfer offer a possible explanation for the higher conductivity of the neutral viologen.
