The synthesis of 4-n-chlorophenyl-4'-n-alkoxythiobenzoates (in short nOSCl) and 4-chlorophenyl-4'-n- alkoxybenzoylthiobenzoates (in short nOOSCl), where n denoted number of carbon atoms in the alkoxy chain of the nOSCl and nOOSCl liquid crystalline compounds have been presented. The substances from nOSCl series show existence of liquid crystals phases in convenient temperature range from uses point of view. The lower homologues possess nematic or nematic and smectic A phases and higher possesses enantiotropic smectic A phase only. The range of smectic A phase changes distinctly upon the elongation of the alkoxy chain. The liquid crystals from the second series, nOOSCl, possess high temperatures of the phase transitions. The temperature ranges of the liquid crystalline phases are distinctly wider for nOOSCl than for nOSCl.
