Construction and Application of a Pepsin‐Functionalized Covalent Organic Framework with Prominent Chiral Recognition Ability

Abstract

The stable Pepsin@covalent organic framework (Pepsin@COF) were constructed base on matching COF pore diameter to pepsin dimension. It exhibits excellent chiral recognition capabilities (e.e.% up to 62.63%) and potential for enantioseparation. Furthermore, a positive correlation between the immobilized enzyme activity and chiral recognition was revealed, offering insights for the design of biocatalytic nanosystems in chiral separation.
