Abstract

The solution properties of hydrophobically modified napthalene (Np)-labeled poly(acrylic acid) (PAA) polyelectrolytes were investigated in water:organic solvent mixtures. The photophysical behavior of the polymers was also investigated using steady-state and time-resolved fluorescence. The emission spectra of the high-labeled Np PAA showed the presence of monomer and excimer bands, while with the low-labeled polymer only monomer emission was found. It was also found that the decay times were dependent on the water content of the mixture.
