Md. Wand et al., NEW CHIRAL DOPANTS BASED ON THE 2-FLUORO-2-METHYLALKOXY TAIL FOR USE IN FERROELECTRIC LIQUID-CRYSTAL MIXTURES, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 263, 1995, pp. 217-222
A new class of PLC materials based on the 2-fluoro-2-methylalkoxy tail
is reported. This new class of materials consistently shows an N hel
ical pitch opposite in sign to that of the polarization. These materia
ls are compared to their 2-fluoroalkoxy analogs to explore the methyl
group's effect on the N pitch and polarization.
