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.

From 4-(trans-4 prime -n-alkylcyclohexyl)-benzoyl chlorides four series of esters were prepared to study the effects of various substituents, especially those in the terminal position, on the phase transition temperatures and enthalpies and on the dielectric constants.
