A Homochiral Poly(2-oxazoline)-based Membrane for Efficient Enantioselective Separation.

February 2023
Chiral separation membranes have shown great potential for the efficient separation of racemic mixtures into enantiopure components for many applications, such as in the food and pharmaceutical industries; however, scalable fabrication of membranes with both high enantioselectivity and flux remains a challenge. Herein, enantiopure S-poly(2,4-dimethyl-2-oxazoline) (S-PdMeOx) macromonomers were synthesized and used to prepare a new type of enantioselective membrane consisting of a chiral S-PdMeOx network scaffolded by graphene oxide (GO) nanosheets. The S-PdMeOx-based membrane showed a near-quantitative enantiomeric excess (ee) (98.

Article Synopsis
- Recent advancements in homochiral metal-organic framework (MOF) membranes show promise for chiral separations, but fabricating high-quality membranes remains challenging due to crystallization difficulties.
- Mixed matrix membranes (MMMs) combine the benefits of MOFs and polymers, and new homochiral MOF-polymer MMMs have been developed for efficient chiral separation.
- By modifying achiral MIL-53-NH nanocrystals with amino acids and incorporating them into a polymer matrix, these MMMs achieved a remarkable enantiomeric excess of up to 100% for separating racemic 1-phenylethanol.
