Title:
REACTIVE LIQUID CRYSTAL COMPOUND, POLYMERIC LIQUID CRYSTAL COMPOUND, LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL ELEMENT
Document Type and Number:
Japanese Patent JP3228348
Kind Code:
B2
Abstract:
PURPOSE: To provide a reactive liquid crystal compound excellent in the film- forming property, permitting to produce liquid crystal elements good in responding properties and having large areas, and capable of giving optoelectric thin films excellent in optical characteristics.
CONSTITUTION: A compound of formula I (R1 is H, alkyl, halogen; U, V, W, X, Y are single bond, -O-, -OCO-, -COO-; (a) is 0, 1; (b), (f) are 0-15; (c), (d), (e) are 0-2), e.g. a compound of formula II. The exemplified compound of formula II is obtained by reacting 6-chloro-hexanol with p-hydroxybenzoic acid and subsequently with acrylic acid and then reacting the produced p-(6- acryloyloxyhexyloxy)benzoic acid with 2,3-dicyano-p-hydroquinone. The compound of formula I and a reactive liquid crystal compound having a polymerizable functional group, e.g. a compound of formula III, are radical- or ionic-copolymerized to provide a polymeric liquid crystal compound.
