Reinvestigation of Mesomorphic Properties of 4,4’-Dialkyl-Biphenyl - New Orthogonal Phases
The phase situation in a few members of 4,4’-dialkylbiphenyl homologous series were investigated. Different orthogonal smectic E phases existing in the temperature range below the smectic B-cryst phase were observed. The simultaneous existence of three different smectic E phases in 4-pentyl 4’-hexylbiphenyl by thermomicroscopic, DSC and rentgenographic methods was confirmed. The miscibility studies were used to assign these phases to other smectic phases existing in other members of this homologous series.
