Abstract

With the use of second-harmonic generation, we report the observation of a better alignment of Langmuir- Blodgett-deposited films of 2-docosylamino-5-nitropyradine for a low number of monolayers. An estimation of the nonlinear susceptibility of the molecule is also given. We show that the refractive indices of the Langmuir-Blodgett films has to be taken into account for thicknesses greater than 25 nm.
