Liquid crystalline compounds containing the -CH2CH2-C ≡ C- inter-ring linkage between cyclohexane and benzene rings belonging to four homologous series have been prepared. Their mesogenic, viscous, dielectric, optical, and dielectrooptical properties were investigated and compared with the properties of analogous compounds with the -CH2CH2- or -C ≡ C- bridge groups. The mesogenic and physical properties of the compounds with the -CH2CH2-C ≡ C- linkage group are intermediate between properties of the compounds with -C ≡ C- and the properties of the compounds with -CH2CH2- group, except that their clearing points are lower and viscosity is higher.
