Abstract

The invention relates to 1,1-disubstituted cyclohexane derivatives containing one or more polymerizable groups, and to liquid-crystalline media comprising at least one compound of the formula I. At least one of the polymerizable groups is located at the geminally substituted position of the cyclohexane ring. The compounds are suitable for the stabilization of liquid-crystalline phases. Examples of polymer-stabilized blue phases are indicated.
