The mesogenic properties of four series of compounds with the isothiocyanate terminal group are compared, viz.: 4-n-alkyl-4'-isothiocyanatobiphenyls /1/, 4-/trans-4'-n-alkyl-cyclohexyl/benzeneisothiocyanates /2/, isothiocyanatophenyl 4-n-alkylbenzoates /3/ and isothiocyanatophenyl 4-/trans-4'-n-alkylcyclohexyl/benzoates /4/.It has been found that compounds 2 have only the nematic phase in the homologous series from 2 to 10 carbon atom in the alkyl chain, and compounds 4 the nematic and smectic A phases, while the so far know compounds 1 and 3 are E or A smectics.
