R. Buchecker et al., NOVEL DOPANTS FOR FERROELECTRIC MIXTURES INCORPORATING CHIRAL DIOXANEOR TETRAHYDROPYRANE RINGS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 302, 1997, pp. 295-301
The synthesis, mesomorphic properties and use as chiral dopants in fer
roelectric mixtures of chiral dioxane and tetrahydropyrane derivatives
are presented. The dioxanes induce a sufficiently high spontaneous po
larisation and a very small pitch if added to achiral Sc-mixtures.
