Induction of chirality by doping mesogens with non-mesogenic chiral dopant

Use of chiral dopant in binary mixtures to induce ferroelectricity / chiral nematic phase is an easier way than the synthesis of ferroelectric or chir al nematic materials. Number of researchers have tried to induce chirality in the achiral mesogens by doping it with naturally occuring chiral compoun ds or their derivatives. Few binary systems were studied where one of the c omponents is the non-mesogenic chiral dopant. In almost all the systems stu died cholesteric phase (N*) is induced with lowering in transition temperat ures. The study provides means to induce chirality in mesogenic system by d oping it with the derivative of naturally occurring chiral menthol.
