Porous organic cage mixed matrix membranes for efficient enantioseparation.

ABSTRACT: Mixed matrix membranes (MMMs) based on homochiral microporous materials have emerged as a promising approach for enantioselective separation. However, constructing MMMs for achieving efficient enantioselective separation at a high feed concentration still remains a great challenge due to the suboptimal interfacial compatibility. Here, we employ soluble porous organic cages (POCs) of intrinsic chiral sites as fillers to fabricate MMMs devoid of interfacial defects, exhibiting fast and selective enantioseparation for racemic 2-phenylpropionic acid with a flux of 2.93×10^-3mol m^-2 h^-1 and an enantiomeric excess (ee) value up to 100% at a high concentration of 0.1 mol L^-1. The POC-based MMMs demonstrate a long-term operation stability with a low ee d
