Abstract

Official abstract text for this publication.

A novel vinyl-group-containing fluorene compound and a method for producing the same, a polymerizable monomer and cross-linking agent including this compound, a leaving-group-containing fluorene compound, a monovinyl-group-containing fluorene compound, and methods for producing the same. This vinyl-group-containing fluorene compound is represented by formula (1). In the formula, W 1 and W 2 represent a group represented by formula (2), a group represented by formula (4), a hydroxyl group, or a (meth)acryloyloxy group, R 3a and R 3b represent a cyano group, a halogen atom, or a monovalent hydrocarbon, and n1 and n2 are integers of 0-4. In formulas (2) and (4), a ring (Z) is an aromatic hydrocarbon ring, X is a single bond or a group represented by —S—, R 1 is a single bond or a C1-4 alkylene group, R 2 is a specific substituent group such as a monovalent hydrocarbon, and m is an integer of 0 or greater.

First claim

Opening claim text (preview).

The invention claimed is: 1. A vinyl-group-containing fluorene-based compound represented by the following formula (1): wherein W 1 and W 2 each independently represent a group represented by the following formula (2), a group represented by the following formula (4), a hydroxyl group, or a (meth)acryloyloxy group, provided that W 1 and W 2 do not simultaneously represent a hydroxyl group or the group represented by the following formula (4), and at least one of W 1 and W 2 represents a group represented by the formula (2); R 3a and R 3b each independently represent a cyano group, a halogen atom, or a monovalent hydrocarbon group; and n1 and n2 each independently represent an integer of 0 to 4, wherein a ring Z represents a fused aromatic hydrocarbon ring; X represents a single bond or —S—; R 1 represents a single bond; R 2 represents substituent group A or B, wherein substituent group A represents a monovalent hydrocarbon group, a hydroxyl group, a group represented by —OR 4a , a group represented by —SR 4b , an acyl group, an alkoxycarbonyl group, a halogen atom, a nitro group, a cyano group, a mercapto group, a carboxyl group, an amino group, a carbamoyl group, a group represented by —NHR 4c , a group represented by —N(R 4d ) 2 , a (meth)acryloyloxy group, or a sulfo group; and substituent group B represents a group formed by substituting at least a part of hydrogen atoms bonded to carbon atoms of the substituents contained in substituent group C below with a monovalent hydrocarbon group, a group represented by —OR 4a , a group represented by —SR 4b , an acyl group, an alkoxycarbonyl group, a halogen atom, a nitro group, a cyano group, a mercapto group, a carboxyl group, an amino group, a carbamoyl group, a group represented by —NHR 4c , a group represented by —N(R 4d ) 2 , a (meth)acryloyloxy group, a mesyloxy group, or a sulfo group, wherein substituent group C represents a monovalent hydrocarbon group, a group represented by —OR 4a , a group represented by —SR 4b , an acyl group, an alkoxycarbonyl group, a group represented by —NHR 4c or a group represented by —N(R 4d ) 2 ; R 4a to R 4d each independently represent a monovalent hydrocarbon group; and m is an integer of 0 or more, and wherein a ring Z, X, R 1 , R 2 , and m are as defined above. 2. The vinyl-group-containing fluorene-based compound according to claim 1 , wherein the ring Z is a naphthalene ring.
