ABSTRACT:
1. A mesomorphic compound represented by the following formula 8 I]: ##STR1## wherein R.sub.1 and R.sub.2 respectively denote a straight chain or branch chain allyl group having 1-18 carbon atoms, wherein --CH.sub.2 -- in the alkyl group may be substituted by ##STR2## on condition that hetero atoms are not adjacent each other, R.sup.2 may be hydrogen atom, halogen atom, cyano group and trifluoromethyl group; n is 0 or 1, with the proviso that A.sup.1 denotes a single bond, ##STR3## when n is 0, A.sup.1 denotes a single bond when n is 1; A.sup.2 denotes any one of ##STR4## and X.sup.1, X.sup.2, Z.sup.1 and Z.sup.2 denote independently any one of hydrogen atom, halogen atom, cyano group and trifluoromethyl group, with proviso that X.sup.1, X.sup.2, Z.sup.1 and Z.sup.2 may not be all hydrogen atoms; Y denotes any one of ##STR5## a single bond.
