    摘要: Nematic phases were obtained by mixing 4-methoxy-4′-stilbazole with structural isomers of methyl-, methoxy-, and halo-benzoic acid derivatives, all the components are rod-like nonmesogens. It was shown by NMR, IR, uv-vis and fluorescent spectroscopic studies that the hydrogen bonds played the central role. Enantiotropic with wide temperature ranges were observed for the mixtures of 4-substituted benzoic acids. The stability of induced mesophase decreased for the mixtures of 3- and 2-substitutions.
