M. Castro et al., ANOMALOUS DIELECTRIC BEHAVIOR IN ORTHOPALLADATED FERROELECTRIC LIQUID-CRYSTALS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 265, 1995, pp. 521-525
A ferroelectric ortho-palladated dimer derived from chiral imines with
two chiral terminal chains in the aromatic ring has been characterize
d by dielectric permittivity, polarization, X ray and heat capacity me
asurements. An anomalous behaviour has been detected in the low temper
ature range of the SmC phase. A new molecular arrangement has been fo
und on cooling prior to the crystallization not detected before by DSC
experiments.
