摘要：

Mixed Langmuir-Blodgett multilayers of N-acyl-p-nitroaniline and its homologous amphiphile, p-alkylaminophenylacetic acid, show second harmonic generation in Y-type films. The second harmonic output was anisotropic to the dipping direction, and depended on the molecular-chain lengths of the mixture. As a model of noncentrosymmetric structure in the Y-type film, the "herringbone"-like arrangement of interlayer molecules was considered. This arrangement of molecules was confirmed by measurements of second harmonic fringing patterns from hetrostructural films with different combination of active and inactive layers.
