ELECTRON-PARAMAGNETIC RESONANCE SPECTROSCOPY OF ELECTRODEPOSITED SPECIES FROM SOLUTIONS OF 1,1'-BIS-(PARA-CYANOPHENYL)-4,4'-BIPYRIDILIUM (CYANOPHENYL PARAQUAT, CPQ)

Abstract:

EPR spectra of electro-reduced CPQ (cyanophenyl paraquat, 1,1-bis-(p-cyanophenyl)-4,4′ -bipyridilium) in radical cation form have been studied in propylene carbonate solution and as solid deposited with various anions from aqueous solution. In either milieu, no hyperfine coupling is seen, and with sulphate the low intensities indicate some dimerisation. Further (solid-state) reduction to CPQ° produced diamagnetic product (contrast solution-phase comproportionation with CPQ2+) except in the pr...
