K. Czuprynski et al., REINVESTIGATION OF MESOMORPHIC PROPERTIES OF 4,4'-DIALKYL-BIPHENYL - NEW ORTHOGONAL PHASES, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 299, 1997, pp. 503-508
The phase situation in a few members of 4,4'-dialkylbiphenyl homologou
s series were investigated. Different orthogonal smectic E phases exis
ting in the temperature range below the smectic B-cryst phase were obs
erved. The simultaneous existence of three different smectic E phases
in 4-pentyl 4'-hexylbiphenyl by thermomicroscopic, DSC and rentgenogra
phic methods was confirmed. The miscibility studies were used to assig
n these phases to other smectic phases existing in other members of th
is homologous series.
