Abstract
Summary form only given. The ionic interaction was applied to construct noncentrosymmetric nonlinear optical(NLO) multilayers - In order to fully utilize such an interaction, stilbene-type NLO chromophores having a sulfonate group at one end of the chromophore were designed. Among such type of the chromophores trans-4´-(4-sulfonic acid sodium salt)butanoxystyrylpyridine(l) was synthesized. A pyridine moiety can be easily methylated to augment the molecular hyperpolarizability(p). The above anionic chromophore was observed to adsorb on the cationic surface prepared with 3-aminopropyltriethoxysilane. Characteristics of the layer have been examined with contact angle measurement, UV-Vis spectroscopy, and NLO property measurement.
