Abstract
Low-molar-mass surfactants (S) and polyelectrolytes (PE) containing di azosulfonate chromophores which are photo-labile and electrically char ged were used for the formation of polyelectrolyte/surfactant complexe s (PESC) in combination with commonly used polyelectrolytes and surfac tants. The stable complexes are no longer water-soluble and were chara cterized by means of nuclear magnetic resonance spectroscopy and in so me cases by means of gel-permeation chromatography measurements. Compl exes with a 1:1 stoichiometry with respect to charge are formed. Ultra violet irradiation of the photo-labile PESC resulted in the loss of th e ionic interactions.
