摘要
Monolayers of the amphiphile 1-monopalmitoyl-rac-glycerol at the air-water interface assemble into domains in which the molecular tilt azimuth is organized into star-shaped patterns. When the domains are transferred to solid supports as Langmuir-Blodgett films, they are capable of producing a macroscopic azimuthal orientation of nematic liquid crystals, which allows the order in the monolayer to be observed by polarized optical microscopy.
