    摘要: The homologues of bis[4-(5-alkyl-1,3-dioxan-2-yl)-phenyl]terephthalate were synthesized. Wide mesophase temperature ranges, nematic for butyl to dodecyl and smectic C for octyl to tetradecyl derivatives, were observed. The trans-cis isomerization of the heterocyclic rings and dissociations of the ester linkages after heating the sample to high temperatures were studied by NMR spectroscopy.
