cis-trans Reversible Photoisomerization of an Amphiphilic Azobenzene Derivative in Its Pure LB Film Prepared as Polyion Complexes with Polyallylamine

Article abstract of DOI:10.1246/cl.1988.1257

By using polyallylamine (PAA) for the aqueous subphase, the pure LB films of an azobenzene derivative with a long alkylchain showed reversible cis-trans photoisomerization due to the relatively large cross section of the molecule determined by the surface density of the ammonium cations of protonated PAA.
