Abstract

Abstract Translated from German Eine Flüssigkristallmischung bestehend aus mindestens zwei Komponenten, die als eine Komponente eine makrocyclische Verbindung der allgemeinen Formel (1) enthält wobei a, b, c, d, e, f unabhängig voneinander eine ganze Zahl von Null bis 4, wobei a + b + c + d + e + f ≧ 7 ist, und -A-, -B-, -C-, -D-, -E-, -F- gleich oder verschieden z.B. -CH₂-, -CH=CH-, -CO- oder -COO- sind, führt in FLC-Displays zur Ausbildung einer uniformen Ausrichtung und zur Vermeidung von Twist-Zuständen, was sich in einem deutlich verbesserten Kontrast niederschlägt. A liquid crystal mixture consisting of at least two components, which contains as one component a macrocyclic compound of the general formula (1) in which a, b, c, d, e, f independently an integer from zero to 4, where a + b + c + d + e + f ≧ 7, and -A-, -B-, -C-, -D-, -E-, -F- are the same or different, for example -CH₂-, -CH = CH-, -CO- or -COO-, leads to the formation of a uniform alignment in FLC displays and the avoidance of twist states, which is reflected in a significantly improved contrast.
