摘要：

Langmuir-Blodgett (LB) films are reported for an amphiphilic disklike mesogene with a nematic liquid crystalline phase in bulk. The molecular arrangement of a discotic smectic-nematic phase, induced in the LB films, is evidenced by means of x-ray diffraction, atomic force microscopy, and UV-VIS (visible) absorption spectroscopy. The disklike molecules are ''edge-on'' arranged with a bilayer periodicity of 4.45 nm normal to the solid substrate and with a nematic arrangement in the monolayer planes. This structure results in extremely smooth top film surfaces.
