We report the use of a chiral Cu(II) 3D metal-organic framework (MOF) based on tripeptide Gly-l-His-Gly (GHG) for enantioselective separation metamphetamine and ephedrine. Monte Carlo simulations suggest that recognition is linked to preferential binding one enantiomers as result either stronger or additional H-bonds with lead energetically more stable diastereomeric adducts. Solid-phase extraction racemic mixture by using Cu(GHG) extractive phase permits isolating >50% (+)-ephedrine...

Abstract A robust and water‐stable metal–organic framework (MOF), featuring hexagonal channels decorated with methionine residues ( 1 ), selectively captures toxic species such as CH 3 Hg + 2+ from water. exhibits the largest uptake capacity ever reported for a MOF, decreasing [Hg ] [CH concentrations in potable water highly hazardous 10 ppm to much safer values of 6 27 ppb, respectively. Just like biological systems, high‐performance metal capture also involves molecular recognition...
Porosity and surface area analysis play a prominent role in modern materials science. At the heart of this sits Brunauer-Emmett-Teller (BET) theory, which has been remarkably successful contribution to field The BET method was developed 1930s for open surfaces but is now most widely used metric estimation areas micro- mesoporous materials. Despite its widespread use, calculation causes spread reported areas, resulting reproducibility problems both academia industry. To prove this, analysis,...
A challenging aspect in the synthesis of covalent organic frameworks (COFs) that goes beyond framework's structure and topology is interpenetration, where two or more independent are mechanically interlocked with each other. Such interpenetrated commonly found three-dimensional (3D) COFs large pores. However, two-dimensional (2D) rarely seen literature, as 2D COF layers typically crystallize stacks maximize stabilization through π-stacking. The few described to date have been derived from...
