The present invention relates to an enantioselective cation-exchange material, comprising a chiral selector (
1
), composed of a chiral component (
2
) and at least one cation-exchange group (X), a spacer (
3
) and a carrier (
4
). The cation-exchange material is characterized in that the chiral component (
2
) has a molecular weight of less than 1,000 and the at least one cation-exchange group (X) is an acid group having a pKa<4.0.
本发明涉及一种对映选择性阳离子交换材料,包括手性选择剂(1),由手性组分(2)和至少一个阳离子交换基团(X)组成,以及一个间隔物(3)和载体(4)。该阳离子交换材料的特点在于,手性组分(2)的分子量小于1,000,至少一个阳离子交换基团(X)是具有pKa<4.0的酸性基团。
