Counterion condensation on a polyelectrolyte: A fluorescence quenching study
 Riedlová, Kamila ; Štěpánek, Miroslav (advisor) ; Humpolíčková, Jana (referee)
In this thesis, we studied the counterion condensation on the polyelectrolyte chain by means of the fluorescence quenching technique, using poly(methacrylic acid) (PMAA) labelled by the naphthyl group either at the end or in the middle of the chain and cesium ions as counterions which act as the fluorescence quencher. Both polymer samples were characterized by dynamic light scattering. The interaction of Cs+ ions with the polyelectrolyte was studied in solvents differing in the dielectric permittivity, using mixtures of water with 1,4-dioxane. The results confirm that fluorescence quenching is enhanced by the counterion condensation and that this process is more pronounced in the case of the naphthyl moiety localized in the middle of the PMAA chain.
