The fluorescence from the St state of pyrene solubilized within the hydrophobic region of sodium dodecyl sulfate micelles has been studied as a function of concentration of some cationic additives to the aqueous phase. At concentrations of added quencher below ca\_ 10v3 mol dm -3 the fluorescence de
Strong quenching of fluorescence of pyrene by N,N-dimethylaniline as well as N,N-dimethyIaniline sulfonate has been observed in aqueous micellar solutions. Photoinduced electron transfer from the aniiines to excited pyrene near the micelIe-water interface has been demonstrated by means of laser phot
Dynamic fluorescence quenching measurements have been performed on pyrene derivatives (pyrene (Py), 1-pyrenebutanoic acid (PBA), and 1-pyrenedodecanoic acid (PDA)), using as quenchers nitroxide free radicals (2,2,6,6-tetramethyl-1,1-piperidinyloxyl, 4hydroxy-2,2,6,6-tetramethyl-1,1-piperidinyloxyl,
The fluorescence quenching of the pyrene derivatives (4-(1pyrenyl)butyl) trimethylammonium bromide (PBTMA), (1-(1pyrenyl)methyl) trimethylammonium iodide (PMTMA), and 1-pyrene sulfonic acid (PSA) by indole methyl substituted in positions 1 and 2, tryptophan and tryptamine, was studied in AOT/ heptan
