Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

In certain chromatographic separations, solutes transfer between the mobile phase and the stationary phase via sorption, which typically refers to the process of adsorption. For many chromatographic systems, the sorption process often depends on the polarity of the compounds—an expression of the overall dipole moment within the molecule. During the separation process, there is competition between the solute and solvent for adsorption to the stationary phase. Highly polar compounds and...

Area of Science:

  • Materials Science
  • Chemistry
  • Nanotechnology

Background:

  • Isoreticular chemistry often relies on increasing framework unit size to enhance pore volume.
  • This approach can be limited in multimodule systems, necessitating quantitative analysis for rational component design.

Purpose of the Study:

  • To synthesize and characterize a broad library of 60 new porous aromatic compound (PACs) metal-organic frameworks (MOFs).
  • To investigate the correlation between unit-cell volume and ligand dimensions within the PACs platform.
  • To evaluate the impact of metal-trimer composition and ligand variations on MOF properties and stability.

Main Methods:

  • Extensive synthesis of new PACs-type MOFs by varying metal-trimer compositions, framework-forming ligands (L1), and pore-partitioning ligands (L2).
  • Quantitative analysis of structural data to establish correlations between unit-cell volumes and ligand lengths.
  • Characterization of material properties, including BET surface area and gas uptake capacity.

Main Results:

  • A broad expansion of the PACs MOF structural library was achieved.
  • A non-monotonic trend between unit-cell volumes and ligand lengths was identified as an intrinsic property of the PACs platform.
  • The NiV trimer demonstrated an amplified stability-enhancing effect in larger pore regimes.
  • New members exhibit record ultrahigh BET surface areas (>4400 m²/g) and exceptional propane uptake capacities, surpassing existing C3H8-selective MOFs.
  • Inverse propane/propylene selectivity was observed, indicating potential for efficient gas separation.

Conclusions:

  • The study provides an experimental basis for understanding the relationship between ligand dimensions and unit-cell volumes in PACs MOFs.
  • The nickel-vanadium trimer is crucial for stabilizing large PACs materials.
  • The developed MOFs show significant promise for high-capacity gas storage and efficient C3H8/C3H6 separations.
