Homochiral metal–organic frameworks (MOFs) have gained much attention because of their chiral properties and disposition for chiral separation. However, the fabrication of high‐quality homochiral MOF membranes remains challenging because of the difficulty in controlling growth of MOF membranes with chiral functionalities. A homochiral zeolitic imidazolate framework‐8 (ZIF‐8) membrane is reported for efficient chiral separation. The membrane is synthesized by incorporating a natural amino acid, l‐histidine (l‐His), into the framework of ZIF‐8. The homochiral l‐His‐ZIF‐8 membrane exhibits a good selectivity for the R‐enantiomer of 1‐phenylethanol over the S‐enantiomer, showing a high enantiomeric excess value up to 76 %.

The gas chromotographic analysis of metal-containing compounds has been a small but reasonably active field for about 25 yeras. Analyses cover such as organometalics, metal complexes, and compounds such as hydrides and halides. Reviews of the fiels may be seen in the books by Moshier and Sievers (1), Guichon and Pommier (2) and Crompton (3), as well as the papers by Uden and Henderson (4) abd Rodrigues-Vasquez (5).
