Abstract: Metal-organic frameworks are synthesized from either a high concentration synthesis where reaction solutions comprising increased reagent concentrations, or suspensions of reagents which exceed their solubility limit in the reaction solution in a high solids synthesis. In both approaches, the solubility of reagent is maximized by inclusion of a buffer, fixing a nominal pH of the reaction solution to allow metal-organic framework formation. These methods improve yields and scale up of metal-organic frameworks.

Abstract: 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.

Abstract: Methods are provided for appending amines to metal organic framework (MOF) compositions. In some aspects, the methods can allow for appending of amines in the solution or synthesis solution used for synthesizing a MOF. In such aspects, an amine-appended MOF can be formed without having to first separate and dry the underlying non-amine-appended MOF composition. In other aspects, amines can be appended to an existing MOF composition by exposing the MOF to a suitable amine in a protic solvent, such as water or an alcohol.
