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...
The Langmuir monolayers of a chloroform soluble dimethoxy substituted precursor poly(p-phenylenevinylene) (PPV) with a methoxy leaving group were studied. During storage in chloroform the precursor polymer is partly converted to PPV. Multilayer films could only be prepared of this partly converted precursor. When a monolayer of this polymer containing 5% PPV units was deposited, an orientation of...
