Molekulares Verdrillungsvermögen von Kohlenhydrat-Derivaten

Abstract

For the first time carbohydrate derivatives were systematically studied as doping material for a liquid crystalline phase. These compounds can exhibit a large twisting power. It may be controlled by the configurations of single chiral centers. Thus, a series of phenomena are realized in the cholesteric phase such as helix inversion, large or small temperature dependencies of the pitch, as well as broad blue phases.
