New Trick For MOFs

Incorporating cyclic polyethers into metal-organic frameworks permits specific binding of organic molecules in the porous materials
Department: Science & Technology
Keywords: metal-organic framework, molecular recognition

By incorporating macrocyclic polyethers into the three-dimensional porous structure of metal-organic frameworks (MOFs), a team of chemists from UCLA and Northwestern University has enhanced the capabilities of MOFs to include specific binding of organic molecules (Science 2009, 325, 855). Thousands of MOFs made up of metal-based joints connected by linear organic struts have been prepared and shown to nonspecifically bind small guest molecules according to their size or shape—adsorbing H2 molecules within the . . .
