At low quencher concentration the Stern\u2013Volmer constant is 94 mol\/L; as the quencher concentration increases the Stern\u2013Volmer plots become superlinear. Ascorbic acid is used to reduce TEMPO to the corresponding hydroxylamine and the PPE\u2013SO<jats:sub>3 <\/jats:sub>fluorescence is fully recovered. Under a large excess of ascorbic acid over TEMPO, the rise of fluorescence followed pseudo\u2010first\u2010order kinetics. The second\u2010order rate constant calculated from this time course is 0.7 mol\/L\/s.
