BORGS: Beyond Open Reticulated Geometries

Tech ID: 21609 / UC Case 2008-378-0

Summary

UCLA scientists have developed porous metal-organic frameworks (MOFs) capable of combining adsorption, conduction, molecular recognition, and switching into one material.

Background

Metal-organic frameworks are crystalline compounds consisting of metal ions or clusters coordinated to often rigid organic molecules to form one-, two-, or three-dimensional structures that can be porous. These structures, while robust, usually contain only passive sites for adsorption, lacking molecular recognition and switching capabilities.

Innovation

Researchers at UCLA have improved MOF structures by creating Beyond Open Reticulated Geometry MOFs (BORG-MOFs) and a method of fabrication. The molecular recognition sites impart selectivity in binding and identifying an incoming agent, while the adjustment of pore metrics allows for size and shape selectivity. Major improvements over current MOF structures include the BORG-MOFs' ease of functionalization of active sites and their ability to combine adsorption, conduction, molecular recognition, and switching into one material. BORG-MOFs also have increased porosity over traditional MOFs, resulting in more receptor sites and increased sensitivity.

Applications

  • Gas separation or purification
  • Sensors
  • Military or personal safety - nerve agent gas and explosion detection

Advantages

  • Combines adsorption, conduction, molecular recognition, and switching
  • Ease to functionalize active sites
  • Increased sensitivity

State Of Development

 Initial synthesis and fabrication of MOF structure is achieved.
