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.

Metal-organic frameworks having localized defects for gas separations

Provided herein are methods of novel methods of synthesizing a metal-organic framework system by vapor-phase appending of a plurality of ligands appended to a metal-organic framework. Also, provided are methods of recycling metal-organic framework systems by detaching the ligand and re-appending the same ligand or appending a different ligand to the metal-organic framework to provide a recycled or repurposed metal-organic framework system.
