A new medium with non-linear optical properties, comprising J-aggregates of cyanine dyes entrapped in a polymer matrix is reported. Pseudoisocyanine and benzothiazolium dyes with C2H5 and C18H37 chains were synthesized; Langmuir-Blodgett and polymer films of these dyes were prepared. The temperature stability of the J-aggregates in films was investigated by optical spectroscopy. J-Aggregates in polymer films display a higher thermal stability than those in Langmuir-Blodgett films and can be used in non-linear susceptibility experiments. The cubic susceptibility of the films was measured by four-wave mixing and found to be 0.8 x 10(-7) cm(3) erg(-1) for the degenerate case, Upon addition of metal clusters to the J-aggregate-polymer composite, an increase by a factor of > 30 in the susceptibility was observed.
