The photophysical behavior of polystyrene sulfonate acridine orange system has been studied. It was found that the fluorescence intensities of acridine orange are strongly dependent on the ratio (P/D) of the dye and the polyelectrolyte used.The maximum fluorescence intensity was observed at (P/D) =100. After correction, this value agreed with the result obtained by Fox et al. in study of energy-transfer of poly(styrene-Co-l-vinylnaphthalene). It indicated that the energy migration occurred efficiently in the...

The photophysical behavior of polystyrene sulfonate acridine orange system has been studied. It was found that the fluorescence intensities of acridine orange are strongly dependent on the ratio (P/D) of the dye and the polyelectrolyte used.The maximum fluorescence intensity was observed at (P/D) =100. After correction, this value agreed with the result obtained by Fox et al. in study of energy-transfer of poly(styrene-Co-l-vinylnaphthalene). It indicated that the energy migration occurred efficiently in the polyelectrelyte-dye complexes.In this paper, the quenching of fluorescence of acridine orange by methylene blue was also studied. The enhancement of quenching effect has been observed after adding polyelectrolyte.
