Abstract
Third-order electric susceptibility chi((3)) of tin-phthalocyanine fil m deposited on a boro-silicated glass plate coated with rubbing-treate d polyimide thin film was measured by a method of THG Maker-fringe tec hnique. In the resonant absorption spectral range, the maximum values of chi((3)) of aggregated tin-phthalocyanine were 220x10(-12)esu obtai ned in the direction perpendicular to the rubbing direction, but the v alues parallel to the rubbing were 47x10(-12)esu. The large \ anisotro py of chi((3)) was induced by a preferred orientation of tin-phthalocy anine microcrystals when anisotropic substrates were heated at 200 deg rees C.
