Abstract
Infinite coordination polymeric (ICP) materials are disclosed. One ICP material has a formula wherein —O(CO)-L-C(O)O— is the ligand, M and M′ are each a metal ion and are the same or different, Sol and Sol′ are each a solvent molecule and are the same or different, x and y are each selected from the group consisting of 0, 0.5, 1, 1.5, 2, 2.5, 3, and 3.5, and n is at least 100. Also disclosed are methods of making the ICP materials and methods of adsorbing a substance by contacting the ICP material with the substance. The substance can be a gas. Further disclosed is a crystalline metallo-ligand complex having a structure
Claims18
A polymeric material comprising metal ions and ligands and optionally one or more solvent molecules coordinated to the metal ions, wherein the polymeric material is amorphous and is capable of adsorbing a gas, and the ligand comprises two carboxylate moieties and at least one chelating moiety other than the two carboxylate moieties.
The method of claim of 13, wherein the polymeric material adsorbs hydrogen to a greater extent than it adsorbs nitrogen.
A metallo-ligand complex having a formula
- wherein the metallo-ligand complex is crystalline, each Sol is independently selected from pyridine, water, and dimethyl formamide, and x and y are each independently selected from the group consisting of 0, 1, 2, and 3.
