A maltose-functionalized metal-organic framework (MOF), MIL-101(Cr)-maltose, was developed via a simple two step post-synthetic modification of MIL-101(Cr)-NH2. With the use of this nanomaterial, 33 glycopeptides were detected from the digest of human immunoglobulin G, demonstrating its high efficiency in glycoproteomic analysis. More importantly, the generic functionalization route from amino-derived MOFs opens a new perspective in material design in sample preparation.

This manuscript explores the post-synthetic modification (PSM) of amine-functionalized porous coordination cages, specifically focusing on the formation of imine bonds through reactions with aldehydes. Targeting various cage topologies, including zirconium-, magnesium-, and molybdenum-based structures, we demonstrate the tunability of cage solubility and porosity through selective functionalization where the proximity of amine groups on the parent cage impacts the extent of modification. The work highlights the reversible nature of imine formation, offering potential applications in solubility switching and mixed-metal solid synthesis.

Tuning Metal-Organic Framework Linker Chemistry for Transition Metal Ion Separations.

ACS Appl Mater Interfaces

Department of Chemical and Environmental Engineering, Yale University, New Haven, Connecticut 06520-8286, United States.

The pressing demand for critical metals necessitates the development of advanced ion separation technologies for circular resource economies. To separate transition metal ions, which exhibit near-identical chemical properties, adsorbents and membranes must be designed with ultraselective chemistries. We leverage the customizability of metal-organic frameworks (MOFs) to systematically study the role of material chemistry in sorption and selectivity of Co, Ni, and Cu.

Glutathione-functionalized covalent organic frameworks@silica as a hydrophilic-hydrophobic balanced mixed-mode stationary phase for highly efficient separation of compounds with a wide range of polarity.

Background: Covalent organic frameworks (COFs) are a highly promising stationary phase for high-performance liquid chromatography (HPLC), but the separation of polar compounds is limited by their low hydrophilicity. Therefore, it is crucial to develop novel COFs-based stationary phases with balanced hydrophilicity-hydrophobicity for the efficient separation of different polar compounds.

Results: In this paper, glutathione (GSH)-functionalized COFs@silica microspheres (GSH-COFs@SiO) were synthesized via a two-step, post-synthesis modification strategy.

Dual metal organic framework post-synthetic modification; two birds with one stone.

Chem Commun (Camb)

December 2024

Simultaneous dual post-synthetic modification was realised in multivariate isoreticular zinc 4,4'-biphenyldicarboxylate frameworks co-loaded with thermo-reactive allyloxy and propargyloxy groups. Radiative heating initiates dual cascade reactions, simultaneously changing both groups under the same conditions with preservation of framework topology and porosity. This work provides a new strategy to target multiple groups in shorter sequences for more efficient metal-organic framework post-synthetic modification.

Article Synopsis
  • Industrial wastewater often contains high levels of mercury, posing serious risks to the environment and human health, and traditional metal-organic frameworks (MOFs) for treatment face handling challenges.
  • The study presents a new method to create MOF composite cellulose aerogels (5MM-101@CA) that demonstrate a high adsorption capacity for mercury (409.84 mg/g) and maintain over 75% removal efficiency after multiple uses.
  • This composite material is also highly sensitive for real-time mercury detection and shows strong fluorescence stability, emphasizing its potential as a low-cost and effective solution for wastewater treatment while minimizing secondary pollution risks.
