Abstract
Low‐molar‐mass surfactants (S) and polyelectrolytes (PE) containing diazosulfonate chromophores which are photo‐labile and electrically charged were used for the formation of polyelectrolyte/surfactant complexes (PESC) in combination with commonly used polyelectrolytes and surfactants. The stable complexes are no longer water‐soluble and were characterized by means of nuclear magnetic resonance spectroscopy and in some cases by means of gel‐permeation chromatography measurements. Complexes with a 1 : 1 stoichiomctry with respect to charge are formed. Ultraviolet irradiation of the photo‐labile PESC resulted in the loss of the ionic interactions.
