Abstract The data from DSC-thermal analysis of a selected number of disubstituted biphenylcyclohexanes is reported. All nonpolar compounds in the series exhibit smectic B-phases, whereas the polar members with e.g. halogenes or cyano groups either only occur in the nematic phase or nematic and smectic A-phase. The phase behaviour and the enthalpies of transition are discussed.
