Title of Invention

A METHOD FOR MAKING COMPOUNDS FOR POLYMERISABLE LIQUID CRYSTALLINE MIXTURES

Abstract

The invention provides compounds of formula (I), wherein A<1> to A<4> are independently selected from the group consisting hydrogen, a methyl group and a hydrocarbon group containing from 2 to 80 carbon atoms in which one or more carbon atoms are optionally replaced by a heteroatom selected from the group consisting -O-, -S- and -N- with the proviso that firstly no two heteroatoms are joined together and secondly that at least one of A<1> to A<4> includes a polymerisable group; B1 represents a hydrocarbon group containing from 4 to 80 carbon atoms, in which one or more carbon atoms are optionally replaced by a heteroatom selected from the group consisting -O-, -S- and -N- with the proviso that no two heteroatoms are joined together; MG<1> and MG<2> are the same or different and each independently represents an aromatic or non-aromatic carbocyclic or heterocyclic ring system containing from 1 to 80 carbon atoms, with the proviso that firstly at least one of MG<1> and MG<2> comprises at least two ring systems and secondly, when MG<1> and MG<2> are identical each of A<1> and A<2> or A<3> and A<4> are different. The invention also provides liquid crystalline mixtures and optical or electro-optical devices including compounds of formula (I).
