The third-order nonlinear optical properties of multilayered films containing 23% by weight of an axially modified silicon phthalocyanine derivative have been measured by degenerate four-wave mixing at 532 nm with 70 ps full width at half maximum pulses. The average [chi][sup (3)]of the films measured at (1.33[plus minus]0.15) [times]10[sup [minus]11] esu using CS[sub 2] as a standard and the cubic hyperpolarizability [l angle][gamma][r angle] was calculated at (1.97[plus minus]0.22)[times]10[sup [minus]32]esu. The degenerate four-wave mixing signal profile indicates that the films have a response time better than 70 ps.
