Title:
COMPOUNDS HAVING ALKYL-SUBSTITUTED ALKENYLENE MOIETY AND LIQUID CRYSTAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/1997/000233
Kind Code:
A1
Abstract:
Compounds of general formula (1), and a liquid crystal composition containing the same, wherein R and R' are each C1-C10 alkyl, cyano, halogeno or the like; A1, A2, A3 and A4 are each a benzene ring, a C3-C8 cycloalkane ring or the like; at least one of Z1, Z2 and Z3 is an alkenylene group of general formula (Q), (wherein P1 and P2 are each hydrogen or C1-C10 alkyl, with at least one of them being C1-C10 alkyl; and q and r are each 0 to 2, the sum of q and r being 2 or below) and the others thereof are each a covalent bond, -CH2CH2- or the like; and m and n are each 0 or 1. The above compounds exhibit a liquid crystal phase over a wide temperature range, are excellent in compatibility with other liquid crystal compounds and stability, and have a high elastic constant ratio K33/K11.
