Abstract
Provided herein are adsorption materials comprising a mixed-metal mixed-organic framework comprising metal ions of two or more distinct metals and a plurality of organic linkers. Each organic linker in the plurality of organic linkers is connected to a metal ion. The adsorption material further comprises a plurality of ligands. In an aspect, each respective ligand in the plurality of ligands is an amine or other Lewis base (electron donor) appended to a metal ion in the two of more distinct elements of the mixed-metal organic framework to provide a mixed-metal mixed-organic framework system.
Claims28
A mixed-metal organic framework having an empirical or chemical formula of two or more distinct metallic elements and bridged by a linker, the mixed-metal organic framework comprising a plurality of disalicylate linkers, wherein each linker comprises one or more aromatic rings, each aromatic ring comprising a carboxylate functional group and an alcohol functional group, the carboxylate functional group and the alcohol functional groups are adjacent to one another on each aromatic ring, and each aromatic ring is positioned at a greatest distance from the other.
A mixed-metal organic framework of the formula:
- M1xM2(2-x)(A) where M1 and M2 are each independently different metal cations, and A is a disalicylate organic linker.
