-
, (2008/06/13)
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) STR1 wherein A represents STR2 X1 and X2, which may be the same or different, each represents STR3 Y represents --O-- or STR4 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.

A compound represented by formula: STR1 In the formula, Ar represents STR2 and each of Ra and Rb independently represents an optically non-active alkyl group or an optically active group having an asymmetric carbon atom. Either Ra or Rb is the optically active group. X represents STR3 Each of l and m represents 0 or 1.

(+)-4-(2-Methylbutoxycarbonyl)phenyl 4-(5-alkyl-1,3-dioxan-2-yl)benzoate (12), (+)-4-(2-methylbutoxy)phenyl 4-(5-alkyl-1,3-dioxan-2-yl)benzoate (11) and the corresponding 1,3-oxathiane (13, 14) and 1,3-dithiane compounds (15, 16) were synthesized.The mesomorphic behaviors of these compounds were measured.Compounds 12 exhibited the ferroelectric liquid-crystal behavior (R= n-C11H23; -4 SmC* 94 deg C), while the corresponding 1,3-oxathiane (13, 14) and 1,3-dithiane compounds (15, 16) did not exhibit such behavior.Therefore, 1,3-dioxane compounds are more favorable for transition of SmA to SmC* than the 1,3-oxathiane or 1,3-dithiane analogs.
