Jf. Li et al., ELECTROOPTIC INVESTIGATIONS OF ENANTIOMERIC MIXTURES OF THE ANTIFERROELECTRIC LIQUID-CRYSTAL TFMHPOBC, Liquid crystals, 23(2), 1997, pp. 255-261
Measurements are reported for the polarization in the ordered phase, a
nd for the tilt susceptibility in the 'disordered' smectic A phase, of
mixtures of left- and right-handed enantiomers of TFMHPOBC. The tilt
susceptibility was found to exhibit a critical exponent gamma = 1.20 /- 0.05, and both its magnitude and the polarization were found to be
nonmonotonic in enantiomeric excess X of S-TFMHPOBC. Their ratio, howe
ver, was found to be approximately constant with X. Several possible e
xplanations are examined.
