Abstract: Provided herein are adsorption materials comprising a metal-organic framework comprising metal ions of metals, a plurality of organic linkers and one or more modulator where each modulator forms a localized defect. Each organic linker in the plurality of organic linkers creates a bridge between metal ions. Each modulator is connected to only one metal chain. The adsorption material further comprises one or more ligands. Each ligand in the plurality of ligands can be an amine or other Lewis base (electron donor) appended to a metal ion of the metal-organic framework.
