Abstract

In order to investigate the separation mechanism of liquid crystals stationary phases based on an oxadiazole moiety, new 1,3,4-oxadiazole derivative as side mesogenic arm in liquid crystals was prepared, and its structural spectroscopic data were studied in this paper. A powerful indication about the relationship between molecular structure and alignment properties is described. Such information is indispensable for the design and synthesis new liquid crystals stationary phases of high separation efficiency.
