摘要：

Polyelectrolyte multilayer assemblies containing azobenzene chromophores using poly(allylamine) derivative bearing azobenzene residues as pendant (Az-PAA) were prepared. The difference in photoresponse of the Az-PAA films and films based on azobenzene-substituted polyanion (PAZO) was discussed. It was observed that photochemical and thermal isomerization in the Az-PAA multilayers were fully reversible.
