The reduction of methyl viologen (MV") and 9,lO-anthraquinone-2-sulfonate (AQS) hy the henzopinacol anion in 50% (v/v) propan-2-ol/water was investigated spectroscopically. The rate constants for these reactions were found to be 12.9 ? 0.2 and 0.23 ? 0.01 M-' s-', respectively.
Methyl viologen forms ion-pair complexes with anionic solutes such as EDTA, hexametaphosphate, acetate, citrate and sulfide ions. The luminescence properties of all complexes are similar, exhibiting an emission maximum centered about 520 nm and an excitation peak at 405 nm. The lifetime of the lumin
