PHOTOELECTROCHEMICAL ELECTRON-SPIN RESONANCE .3. THE REDUCTION OF FLUORESCEIN - A PHOTO-DISP2 REACTION

Abstract:

The reduction of the dye fluorescein in an aqueous solution of high pH (13), at mercury-plated electrodes, has been investigated using in situ electrochemical e.s.r. and a channel electrode flow cell. In the dark, a simple reversible one-electron reduction is observed leading to the formation of the stable semi-fluorescein radical anion. On irradiation with 390 nm light, appreciable photocurrents are observed and the process takes on the characteristics of a DISP reaction with the formation o...
