ABSTRACT:
The present invention is related to photochemically polymerizable liquid crystals of the general formula ##STR1## wherein A.sup.1, A.sup.2 and A.sup.3 are, independently, photochemically polymerizable mesogenic residues. The present invention also provides liquid crystalline mixtures which contain these compounds, as well as use of these compounds in the cross-linked state as optical or electronic components.
