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 χ(3)of the films measured at (1.33±0.15) ×10-11 esu using CS2 as a standard and the cubic hyperpolarizability 〈γ〉 was calculated at (1.97±0.22)×10-32esu. The degenerate four-wave mixing signal profile indicates that the films have a response time better than 70 ps.
