Abstract

A compound of formula (I), wherein G1 and G2 independently represent a polymerisable mesogenic residue; X represents a group selected from -CH2-, -O-, -CO-, -COO-, -OOC-, -CONR'-, -OCOO-, -OCONR'; Sp represents a group of the formula -(CH2)p- in which p is an integer of 1 to 18 and in which one or two non adjacent -CH2- groups are optionally replaced by -CH=CH-; or in which one or two -CH2- groups are optionally replaced by one or two groups selected from the group consisting of -O-, -CO-, -COO-, -OOC-, -CONR'-, -OCOO-, -OCONR' with the proviso that firstly the spacer group does not contain two adjacent heteroatoms and secondly when X is -CH2-, p can also have a value of 0; and M represents an achiral group of formula (II) in which A and B independently represent an optionally substituted six membered isocyclic or heterocyclic group or naphthalenediyl; C is selected from the group consisting of an optionally substituted five and six membered isocyclic or heterocyclic group or naphthalenediyl; n1 and n2 are 0 or 1 with the proviso that firstly 1m(F)n1+n2m(F)2 and secondly, when C is naphthalenediyl 0m(F)n1+n2m(F)2; Z1 is selected from the group consisting of -O-, -COO-, -OOC-, -CO-, -CONR'-, -NR'CO-, OCOO-, -OCONR'-, -NR'COO- and a single bond; in which R' is selected from the group consisting of hydrogen, a lower achiral alkyl group and a lower achiral alkenyl group; Z2 and Z3 are independently selected from the group consisting of single bond, -COO-, -OOC-, -CH2-CH2-, -CH2O-, -OCH2-, -CH=CH-, -Cm(Z)C-, -(CH2)4- and -(CH2)3O-; and R1 is selected from the group consisting of -CN, -COR, -COOR, -OCOR, -CONR'R, -NR'COR, OCOOR, -OCONR'R, -NR'COOR, -F, -Cl, -CF3, -OCF3, -OR and -R in which R is selected from the group consisting of hydrogen, an achiral C1-18 alkyl group and an achiral C4-18 alkenyl group with the double bond at 3-position or higher; and R' is as defined above; with the proviso that at most one of the rings A, B and C is a naphthalenediyl group is provided as well as liquid crystalline mixtures, films and electro-optical devices comprising the compound.
