摘要：

Complexes of azobenzene bearing ammonium amphiphiles and rigid rod-like polyelectrolytes can be formed at the air-water interface. Complexation leads to a stabilization of the monolayer and to an enlarged area per amphilic molecule at high pressures. In contrast to the amphiphile on pure water forming homogeneous monolayers, the monolayers of the complexes have a distinct domain structure as determined by Brewster angle microscopy. Orientation relative to the water surface and aggregation of the chromophores has been investigated via UV-vis spectroscopy. It was found that besides the amphiphile, the structure of the polymer determines monolayer properties. (C) 1998 Elsevier Science S.A. All rights reserved.
