“…Because of a stronger binding energy, (R)-enantiomer is more predominantly adsorbed than (S)-enantiomer, which is consistent with experiment. Our previous simulation studies 52,53 also revealed that the interaction between enantiomer and chiral adsorbent is crucial in enantioselective adsorption. Furthermore, Supplementary Fig.…”

The separation of racemic molecules is of substantial significance not only for basic science but also for technical applications, such as fine chemicals and drug development. Here we report two isostructural chiral metal-organic frameworks decorated with chiral dihydroxy or -methoxy auxiliares from enantiopure tetracarboxylate-bridging ligands of 1,1 0 -biphenol and a manganese carboxylate chain. The framework bearing dihydroxy groups functions as a solid-state host capable of adsorbing and separating mixtures of a range of chiral aromatic and aliphatic amines, with high enantioselectivity. The host material can be readily recycled and reused without any apparent loss of performance. The utility of the present adsorption separation is demonstrated in the large-scale resolution of racemic 1-phenylethylamine. Control experiments and molecular simulations suggest that the chiral recognition and separation are attributed to the different orientations and specific binding energies of the enantiomers in the microenvironment of the framework.

Zeolite membranes – a review and comparison with MOFs

et al. 2015

View full text Add to dashboard Cite

aThe latest developments in zeolite membranes are reviewed, with an emphasis on the synthesis techniques, including seed assembly and secondary growth methods. This review also discusses the current industrial applications of zeolite membranes, the feasibility of their use in membrane reactors and their hydrothermal stability. Finally, zeolite membranes are compared with metal-organic framework (MOF) membranes and the latest advancements in MOF and mixed matrix membranes are highlighted.

“…However, polymer membranes usually bear a trade-off between selectivity and permeability [15]. Due to the good affinity of their structures with polymer chains, MOF particles are considered as good fillers for the fabrication of mixed matrix membranes (MMMs) toward gas separation [10]. Although the related investigation on polymer/MOF composite membranes is still in an early stage, some computational studies have shown that such types of MMMs can exhibit great superiority over the corresponding pure polymeric membranes [16,17].…”

“…Metal-organic frameworks (MOFs), as a novel class of crystal nanoporous materials, have attracted tremendous interest in the membrane-based gas separation and purification during the past decade [7][8][9][10]. Considering the large number of existing materials, it would be very time consuming to experimentally examine the separation properties of new MOF-based membranes.…”
