Biomineralization of enzymes inside rigid metal-organic frameworks (MOFs) is appealing due to its biocompatibility and simplicity. However, this strategy has hitherto been limited to microporous MOFs, leading to low apparent enzymatic activity. In this study, polysaccharide sodium alginate is introduced during the biomineralization of enzymes in zeolitic imidazolate frameworks (ZIFs) to competitively coordinate with metal ions, which endows the encapsulated enzyme with a 7-fold higher activity than that in microporous ZIFs.

Adsorption is an efficient and highly selective method for gold recovery. Introducing rich N/S organic groups to combine with metal-organic frameworks (MOFs) as adsorbents is regarded as a practical and efficient approach to enhance gold recovery. Herein, a MOF (zirconium isothiocyanatobenzenedicarboxylate MOF, UiO-66-NCS) was designed to combine with amidinothiourea (AT) to form UiO-66-AT (zirconium amidothiourea-benzenedicarboxylate MOF) for efficient and rapid adsorption.

During the oxygen evolution reaction (OER), metal-organic framework (MOF) catalysts undergo structural reorganization, a phenomenon that is still not fully comprehended. Additionally, designing MOFs that undergo structural reconstruction to produce highly active OER catalysts continues to pose significant challenges. Herein, a bimetallic MOF (CoNi-MOF) with carboxylate oxygen and pyridine nitrogen coordination has been synthesized and its reconstruction behavior has been analyzed.

Fluorescent metal-organic frameworks (MOFs) are promising sensing materials that have received much attention in recent years, in which the organic ligand conformation changes usually lead to variations of their sensing behavior. Based on this, in the present work, perylene diimide (PDI) derivatives with excellent photochemical properties closely related to their conformation and molecule packing fashion were selected as organic linkers to detect sarin simulant diethyl chlorophosphate (DCP). By the coordination interactions with large lanthanide cations through terminal carboxylate groups from the PDI derivative, a series of one-dimensional coordination polymers, named [Ln(PDICl-2COO)(μ-O)(DMF)] (SNNU-112, Ln = Yb/Tb/Sm/Nd/Pr/Gd/Eu/Er/Ce, PDICl-2COOH = ,'-bis(4-benzoic acid)-1,2,6,7-tetrachlorohydrazone-3,4,9,10-tetracarboxylic acid diimide) were synthesized.

A novel antimonotungstate (AT)-based heterometallic framework {[Er(HO)][Fe(Hpdc)(B-β-SbWO)]}·50HO (, Hpdc = pyridine-2,5-dicarboxylic acid) was obtained through a synergistic strategy of in situ-generated transition-metal-encapsulated polyoxometalate (POM) building units and the substitution reaction. Its structural unit is composed of a tetra-Fe-substituted Krebs-type [Fe(Hpdc)(B-β-SbWO)] subunit and two [Er(HO)] cations. This subunit can be regarded as a product of carboxylic oxygen atoms of Hpdc ligands replacing active water ligands in the [Fe(HO)(B-β-SbWO)] species.
