N. Scaramuzza et Mc. Pagnotta, EVIDENCE FOR FLEXOELECTRIC EFFECTS IN PALLATED METALLORGANIC LIQUID-CRYSTALS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 239, 1994, pp. 263-267
We report the first observation of flexoelectricity in a new class of
liquid crystalline materials: the metallorganic liquid crystal azocomp
ound obtained by complexation with palladium. From our experimental da
ta we can estimate both the values of the flexoelectric constants \e\
= \e(1) - e(3)\ and of the viscosity coefficient gamma(1). The obtaine
d value of \e\ for these unusual materials are found to be similar to
that of usual nematics.
