Abstract (en)
[origin: WO0031211A1] A compound of formula (I), in which R<1> represents a chiral or non-chiral, branched or straight chain C1-20 alkyl or C1-20 alkenyl, which may be optionally substituted by one or more halogen atoms and in which one or more non-adjacent -CH2- groups may be optionally replaced by -CH=CH-, -O-, -CO-, -COO-, -OOC-, -O-OC-O- or -S-; R<2> represents a chiral or non-chiral, branched or straight chain C1-20 alkoxy, C1-20 alkenyloxy, C1-20 alkylcarbonyloxy (alkyl-COO-) or C1-20 alkenyl carbonyloxy (alkenyl-COO-), which may be optionally substituted by one or more halogen atoms and in which one or more non-adjacent -CH2- groups may be optionally replaced by -CH=CH-, -O-, -CO-, -COO-, -OOC-, -O-OC-O- or -S-;MG<1> represents a group of formula (Ia):-(A-Z<2>)n-(B-Z<3>)m, in which A and B are each independently a 1,4-phenylene or 1,4-cyclohexylene group, which may each be optionally substituted by halogen, cyano or nitro or a group of formula R<1> and in which one or two non-adjacent -CH- or -CH2- groups may be optionally replaced by nitrogen or oxygen respectively; Z<1>, Z<2>, Z<3> independently represent a single bond, -COO- or -OOC-, -CH2CH2-, -CH=CH-, -CC-, -OCH2- or -CH2O-;m and n are each independently 0 or 1; and MG<2> represents a 1,4 phenylene group which may be optionally substituted by halogen, cyano or nitro or a group of formula R<1> and in which one or two non-adjacent -CH- groups is replaced by nitrogen is provided. The compound is useful in the preparation of ferroelectric liquid crystal devices.
