A new synthetic method of 4-alkoxy-2-X-benzenethiols (X = H, halogens, CH3) has been established. In order to confirm the validity as a component of liquid crystal materials, some derivatives of S-(4-alkoxy-2-X-phenyl) 4-R-thiobenzoates (R = CnH2n+1O, CN, NO2, X = halogens, CH3) were prepared. Most of the thioesters exhibit a nematic phase, while the lateral substituents (X) tend to reduce the mesophase thermal stability as well as the melting point. The effect of lateral substituents on the mesomorphic properties is discussed.
