AMINE DERIVATIVES AND PROCESS FOR PRODUCING THE SAME

摘要

An amine derivative having a liquid crystal property over a wide temperature range and a process for production thereof are disclosed, the amine derivative being represented by formula (I) <IMAGE> (I) wherein A represents <IMAGE> X1 and X2, which may be the same or different, each represents <IMAGE> Y represents -O- or <IMAGE> R1 and R3, which may be the same or different, each represents a straight chain or branched chain alkyl group having 1 to 18 carbon atoms; R2 represents a hydrogen atom or a methyl group; m and n each represents 0 or 1; and p and q each represents 1 or 2, provided that p and q are 1 when n is 0, and p and q are not 2 at the same time when n is 1.
