    摘要: Various oligoethylene glycols were used to replace the alkyl chain of p-alkyloxybenzoic acid and 4-alkyloxy-4′-stilbazole. The compounds obtained were nomesogenic or monotropic. Mesophases were observed via the formation of hydrogen bond between these proton donors and acceptors, but with narrower mesophase temperature ranges as compared to those of parent mixtures. These effects were attributed to the curving conformation of the ethylene glycol unit as suggested from the results of model calculation.
