Optical charge transfer in the ion pairs methyl viologen2+ guanosine-5′-monophosphate2− and adenosine-5′-triphosphate2−

Abstract

The aqueous ion pairs MV2+ GMP(2-) and MV(2+)ATP(2-) with MV2+ = methyl viologen(2+), GMP(2-) = guanosine-5'- monophosphate(2-) and ATP(2-) = adenosine-5'-triphosphate(2-) display anion to cation outer-sphere charge transfer (OSCT) absorptions at lambda (max) = 406 and 350 nm, respectively, in their electronic spectra.
