Carbohydrate-based liquid crystals: new compounds showing re-entrant TGBA and cholesteric phases and dopant-induced TGBA, SA and SC* phases
Abstract
Re-entrant TGBA and cholesteric phases are observed in a homologous series of pure chiral carbohydrate-based compounds, and contact preparation induces SA phases between cholesteric and nematic compounds as well as re-entrant and Sc* phases in two substances which in pure form only show cholesteric and SA phases.
