Vf. Petrov et al., NEW LIQUID-CRYSTALLINE PYRIDINE-DERIVATIVES, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 265, 1995, pp. 47-53
Several new classes of mesogenic heterocyclic liquid crystals with dif
ferent terminal groups are presented. Their material properties are in
vestigated and compared with those of 2,5-disubstituted pyridine deriv
atives. New compounds are found to exhibit broader temperature ranges
and higher transition temperatures than their analogs. Data also repor
ted on our structural investigations (X-ray scattering) which revealed
the correlation with physico-chemical properties of new 2,6-disubstit
uted pyridine derivatives.
