Abstract

Disclosed is a separating agent for optical isomer which is excellent in optical separation ability. Specifically disclosed is a separating agent for optical isomer containing: an inclusion complex including a π-conjugated polymer in a polymer compound having a hydroxy group or an amino group; and a carrier, the inclusion complex being carried by the carrier.

Claims

1. A separating agent for optical isomers, comprising:

an inclusion complex including a π

-conjugated polymer in a polysaccharide, without a covalent bond between the π

-conjugated polymer and the polysaccharide; and

a carrier, the inclusion complex being carried by the carrier.

2. The separating agent for optical isomers according to claim 1, wherein the polymer compound is amylose and the π

-conjugated polymer is polyphenylenevinylene.

3. The separating agent for optical isomers according to claim 2, wherein the inclusion complex is obtained by polymerizing, in a solution in which amylose is dissolved, a monomer that produces a constitutional unit represented by the following formula (I) after the polymerization

4. The separating agent for optical isomers according to claim 3, wherein the monomer that produces the unit represented by formula (I) after the polymerization is p-xylylenebis(tetrahydrothiophenium)dichloride.

5. The separating agent for optical isomers according to claim 1, wherein at least part of the hydroxy group or amino group of the polysaccharide is modified with a compound having a functional group which acts on an optical isomer.

6. The separating agent for optical isomers according to claim 5, wherein the compound having a functional group which acts on an optical isomer is introduced through a urethane bond, a urea bond, an ester bond, or an ether bond.

7. The separating agent for optical isomers according to claim 6, wherein the compound having a functional group which acts on an optical isomer is a compound that produces an atomic group represented by the following general formula (II) or (III) when introduced into the at least part of the hydroxy group or amino group of the polysaccharide:

—

CO—

R′

 

 

(II)

—

CO—

NH—

R′

 

 

(III)

wherein in the formulae (II) and (III), R′

represents an aliphatic or aromatic hydrocarbon group, which may contain a heteroatom, and the aliphatic or aromatic hydrocarbon group may be unsubstituted or may be substituted with one or more groups selected from the group consisting of a hydrocarbon group which has 1 to 12 carbon atoms and which may contain a heteroatom, an alkoxy group which has 1 to 12 carbon atoms and which may contain a heteroatom, a cyano group, a halogen group, a hydroxy group, a nitro group, an amino group, and a dialkylamino group containing two alkyl groups, each alkyl group having 1 to 8 carbon atoms.

8. A separating agent for optical isomers according to claim 7, wherein the compound having a functional group which acts on an optical isomer is 3,5-dimethylphenyl isocyanate.
