• Effects of solution pH and molecular oxygen on the quantum yields of methylene blue-sensitized photolysis of diazonium salt have been studied in aqueous solutions, using thioacetamide as an activator. The quantum yield increased with an increase in pH when other parameters were kept constant. The presence of oxygen at pH (<7) promoted dye sensitization, but at pH (>7) dominance of the pathway of oxygen quenching of the excited dye triplet caused its suppression. The polymerization of acrylamide in the deaerated solution was readily initiated by dye-sensitized photolysis. A mechanism involving an electron transfer to diazonium cation from unprotonated semimethylene blue formed by a photoredox reaction between excited triplet dye and thioacetamide was in line with these observation.
