Comb-shaped polymers, comprised of hydrophilic backbones and dye-containing, hydrophobic side chains are synthesized for use in multilayered, noncentrosymmetric, thin films by means of Langmuir-Blodgett processing techniques. The second harmonic signal generation exhibited by these films increases quadratically with the number of layers of polymeric dye in the film.
