KRISTALLIN-FLUESSIGE ESTER DES 3 SS-HYDROXY-5 (ALPHA) -CHOLESTAN- 6 ONS FUER GEMISCHE MIT FERROELEKTRISCHEN EIGENSCHAFTEN

摘要

Esters of 3 ???-hydroxy-5 alpha -cholestan-6-one to the general formula I <IMAGE> in which R has the meaning shown in the documents of the description are used as crystalline liquid compounds. The oompounds are used as additives for mixtures with ferroelectric properties, which are used as a medium for producing rapidly switching optoelectronic components having storage properties for depicting figures, symbols and illustrations. After fusion, these substances form smectic and cholesterinic phases over a wide range of temperatures.
