Paper Abstract

Optical linear (polarized UV-visible absorption) and nonlinear (rotation-angle second harmonic generation) measurements on Y-type hemicyanine/arachidic acid interleaving Langmuir-Blodgett multilayers verified that the dipping-induced in-plane molecular alignment was enhanced with increasing dipping speed or layer number. We gave the first direct evidence for the interlayer-enhancement of flow orientation in LB multilayers.
