摘要

PROBLEM TO BE SOLVED: To obtain a new compound capable of providing a liquid-crystalline polymer useful as an optical material, a displaying material, a recording material, etc., by polymerization. ;SOLUTION: This compound is represented by formula I [R¹ is H or methyl; 1 is 0-8; (m) is 0 or 1; rings A to F are each an aromatic, an alicyclic hydrocarbon 6-membered ring or a heterocyclic 6-membered ring; Z¹, Z², Z⁵ and Z⁶ are each a direct bond or CH₂O etc.; (n), (p), (q), (r), (s) and (t) are each 0 or 1; R² is H, a 1-8C alkyl, etc.; X¹ and X² are each H, a halogen, etc.; (n+p+q+r+s+l) is 1-3], e.g. a compound of formula II. The compound of formula I is obtained by reacting trans-1,4-cyclohexanedimethanol with methyl iodide in the presence of sodium hydride catalyst and reacting the product with hydroquinone monoacetate with triphenylphosphine and azodicarboxylic acid diisopropyl, hydrolyzing the resultant product with potassium hydroxide to synthesize trans-4-(4'methoxymethyl)cyclohexylmethyloxyphenol and reacting the product with 4-(methacryloxyethyloxy)benzoic acid.;COPYRIGHT: (C)1998,JPO
