Liquid crystal compounds

Compounds of formula I: wherein the variables are defined as explained in the disclosure. The invention also provides liquid crystalline mixtures and optical or electro-optical devices including compounds of formula (I).

POLYMERIZABLE COMPOSITION SHOWING LIQUID-CRYSTAL PHASE AND OPTICALLY ANISOTROPIC OBJECT MADE WITH THE SAME

An object of the present invention is to provide a polymerizable liquid crystal composition incorporating a polymerizable liquid crystal compound which displays a low nematic phase temperature, displays excellent compatibility with other polymerizable liquid crystal compounds, and furthermore yields a product following polymerization, of good transparency and high mechanical strength. A polymerizable composition is provided which displays a liquid crystal phase, and moreover incorporates a liquid crystal backbone with two or more ring structures and a compound with a partial structure represented by the general formulaP-S-A-D-E- [wherein P1 represents a polymerizable functional group; S1 represents -(CH2)w-, - O(CH2)w-, -(CH2)wO-, -(CH2)wC(=O)O-, -(CH2)wOC(=O)-, -C(=O)O(CH2)w- or - OC(=O)(CH2)w- (w: 1 to 20); A1 and E1 each represent a hydrocarbon ring or a hetero ring, although E1 is a ring incorporated within the liquid crystal backbone; and D1 represents - C(=O)-O-(CH2)m-O-, -O(CH2)m-O-C(=O)-, -O-C(=O)-(CH2)m-O-, or -O(CH2)m-C(=O)-O- (m: 1 to 15)].

Liquid crystalline compounds

The invention provides compounds of formula I: whereinA1 to A4are 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 A1 to A4 includes a polymerisable group;B1represents 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;MG1 and MG2are 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 MG1 and MG2 comprises at least two ring systems and secondly, when MG1 and MG2 are identical each of A1 and A2 or A3 and A4 are different. The invention also provides liquid crystalline mixtures and optical or electro-optical devices including compounds of formula (I).
