摘要

Abstract

As one of the most popular polysaccharide derivatives with high chiral recognition ability

cellulose tris(3

5-dimethylphenylcarbamate) (CDMPC) has been successfully applied in the enantioseparation of a wide range of racemates for various purposes. However

the derivative is usually synthesized with an amorphous structure

and its effect on enantioseparation ability remains obscure. To obtain a better understanding of the correlation between its structure and enantioseparation abil

ity

in this study

CDMPC derivatives with crystalline and amorphous structures were prepared through carbamoylation followed by anti-solvent precipitation. Their chiral recognition abilities were evaluated using high-performance liquid chromatography (HPLC) with chiral stationary phases (CSPs). Interestingly

the ordered arrangement of the helical polymer chains of CDMPC was effectively induced by the aromatic solvent after derivatization

forming a crystalline derivative (

CDMPC

) with a uniform and compact worm-like morphology

whereas the amorphous derivative (

CDMPC

) was obtained by regular treatment with a polar alcoholic solvent. The

CDMPC

–based CSP exhibited higher chiral recognition abilities with much shorter retention times for most racemates in this study

compared to the

CDMPC

–based CSP. In particular

flavanone (

Rac

)

an important chiral drug with anti-inflammatory

anti-tumor

and cardiovascular protective activities

was even better resolved with higher enantioselectivity on crystalline

CDMPC

than on Chiralcel OD

a commercialized chiral column based on CDMPC. This indicates that the crystalline ordered arrangement played a critical role in the chiral recognition ability of the cellulose derivative.
