Abstract
Official abstract text for this publication.
Provided are a novel amylose derivative which exhibits excellent optical isomer separability and which is suitable as an optical isomer separating agent; and an optical isomer separating agent containing the amylose derivative. A task is attained by an amylose derivative having a constituent unit represented by formula (I) below; In below formula (I), R 1 is a substituent group represented by any of formulae 1 to 3 below, and R 2 is a substituent group represented by any of formulae a to g below. R 1 and R 2 are different substituent groups. A combination of R 1 and R 2 in which R 1 is a substituent group represented by structural formula 3 and R 2 is a substituent group represented by structural formula c is excluded from the formula (I).
First claim
Opening claim text (preview).
What is claimed is: 1. An amylose derivative having a constituent unit represented by formula (I) below: wherein, in formula (I), R 1 is a substituent group represented by any of structural formulae 1 to 3 below, R 2 is a substituent group represented by any of structural formulae a to g below, and two R 2 groups are the same substituent group, R 1 and R 2 are different substituent groups, and a combination of R 1 and R 2 in which R 1 is a substituent group represented by structural formula 3 and R 2 is a substituent group represented by structural formula c is excluded from the formula (I) 2. The amylose derivative according to claim 1 , wherein R 1 is a substituent group represented by the structural formula 1 and R 2 is a substituent group represented by any of the structural formulae a, b, e and f in the constituent unit represented by the formula (I). 3. The amylose derivative according to claim 1 , wherein R 2 is a substituent group represented by the structural formula 2 and R 2 is a substituent group represented by any of the structural formulae a, c, d, e and g in the constituent unit represented by the formula (I). 4. The amylose derivative according to claim 1 , wherein R 1 is a substituent group represented by the structural formula 3 and R 2 is a substituent group represented by any of the structural formulae a, b, d, e and f in the constituent unit represented by the formula (I). 5. An optical isomer separating agent, which is constituted from a carrier and the amylose derivative according to claim 1 which is carried by the carrier.
