(top) Stern-Volmer luminescence quenching of *A in the presence of varying concentrations of N-propyl-4-methoxybenzenesulfonamide. (middle) Cyclic voltammograms of 4-methoxybenzenesulfonamide (2.5mM) in CH2Cl2 containing 0.1M NBu4PF6 and varying concentrations of NBu4OP(O)(OBu)2. Ag reference electrode, glassy carbon working electrode, Pt mesh counter electrode were used. Scan rate: 0.1 V/s. (bottom) Cyclic voltammograms of 4-methoxybenzenesulfonamide (2.5mM) and of NBu4OP(O)(OBu)2 (5mM) in CH2Cl2 containing 0.1M NBu4PF6. Ag reference electrode, glassy carbon working electrode, Pt mesh counter electrode. Scan rate: 0.1 V/s.
