Title:
TETRACYCLIC COMPOUND HAVING LATERAL HALOGEN SUBSTITUENT GROUP AND LIQUID CRYSTAL COMPOSITION
Document Type and Number:
Japanese Patent JP2010111686
Kind Code:
A
Abstract:
To provide a new liquid crystal composition having a wide nematic phase temperature range at the same time having high compatibility with other liquid crystallin compounds at low temperature, a large refractive index anisotropy value and chemical stability.
There are disclosed the compound represented by general formula (1) and the liquid crystal composition comprising the same. Wherein H1-H12 represent each H and at least one of them is substituted with a halogen atom and when either one of H6 and H8 is substituted with a halogen, at least one in the remaining H1 to H12 is substituted with a halogen, R1 and Y1 are each independently a 1-20C alkyl, etc., X1, X2, X3 are each independently a covalent bond, 1, 2-ethylene or 1, 4-butylene.
