Abstract
Nematic liquid crystalline mixtures, which can be used in optoelectronic components. Compounds are provided which influence the characteristics of mixtures in the direction of high clarification temperatures at simultaneous favorable switching times. It has been found that compounds of the general formula ##STR1## wherein n, m=1 to 10 in nematic mixtures in quantities of 5 to 40% considerably increase the clarification points without significantly increasing the viscosity, so that favorable switching times are obtained. The new mixtures can be used for the production of optoelectronic components (displays) for watches, computers and other devices.
