We have studied the nonlinear optical properties of Langmuir-Blodgett films of several chiral 1,1'-binaphthyl-based helical polymers. We have studied the nonlinear optical properties and the quality of the Langmuir-Blodgett films. One of the compounds forms high-quality Langmuir-Blodgett films with a high nonlinear susceptibility that remains stable in time. We show that an important part of the nonlinear susceptibility is only allowed by the chirality of the film. (C) 1999 Elsevier Science B.V. All rights reserved.
