Abstract

Abstract: Chiral ZIF‐8 hollow nanospheres withd ‐histidine as part of chiral ligands (denoted as H‐d ‐his‐ZIF‐8) were prepared for separation of (±)‐amine acids. Compared to bulkd ‐his‐ZIF‐8 without a hollow cavity, the prepared H‐d ‐his‐ZIF‐8 showed 15 times higher separation capacity and higher ee values of 90.5 % for alanine, 95.2 % for glutamic acid and 92.6 % for lysine, respectively. Abstract : How to approach a separation : Chiral ZIF‐8 hollow nanospheres withd ‐histidine as part of chiral ligands were prepared for separation of (±)‐amine acids with high separation capacity and excellent ee values.
