e report the first study of time-resolved third-order non-linear optical susceptibilities χ(3) of Langmuir-Blodgett (LB) films formed with ZnP(N+C22)4/H2Pc TS4− * χ(3) of LB films was investigated by non-degenerate four-wave mixing technique with femtosecond time resolution. The LB films was excited at 620 nm and probed at 650nm. This porphyrin-phthalocyanine mixed dimer has a χ(3) with three temporal components related to three excited state populations.
