Microporous Metal-Organic Framework Materials for Sensing and Separation of Gas or Solvent Molecules
Description
The present invention introduces a novel metal-organic framework (MOF) and a novel mixed metal-organic framework (M'MOF) for selective gas storage, selective gas sorption and/or separation, selective sensing of chemicals, and catalysis.
Problem
Although thousands of MOFs and M′MOFs have been synthesized and structurally characterized over the past few decades, very few MOFs have been shown to be useful for selective sorption, separation and/or sensing of guest molecules.
Solution
This invention offers superior methods for gas separation by introducing a novel rod packing microporous MOF with repeating unit Zn4(OH)2(1,2,4-BTC)2 which uses open metal sites and a novel M'MOF with repeat unit Zn3(BDC)3[Cu(SalPyCy)] or Zn3(CDC)3[Cu(SalPyCy)] with chiral pores/pockets.
Value Proposition
These technologies presents MOFs exhibits highly selective sorption and separation of gases due to their unique micropore features.
