Abstract
The technique of polycation/polyanion layer-by-layer adsorption was applied to fabrication of non-linear optical films. Optical second-harmonic generation (SHG) was clearly observed from the films prepared by alternate adsorption of polycations and an azobenzene-containing polyanion (PAZO) on quartz substrate modified with polyion precursor. Regular film growth during adsorption cycles was proved by means of UV spectroscopy and quartz crystal microbalance technique. The SHG signal increased with the number of PAZO layers up to four layers, while further assembly reduced the signal. The SHG decreased considerably by heating the film up to 120°C.
