TLDR
The rapid increase in reports on PSM demonstrates this methodology will play an increasingly important role in the development of MOFs for the foreseeable future, and in both scope of chemical reactions and range of suitable MOFs.Abstract:
The modification of metal–organic frameworks (MOFs) in a postsynthetic scheme is discussed in this critical review. In this approach, the MOF is assembled and then modified with chemical reagents with preservation of the lattice structure. Recent findings show amide couplings, isocyanate condensations, ‘click’ chemistry, and other reactions are suitable for postsynthetic modification (PSM). In addition, a number of MOFs, from IRMOF-3 to ZIF-90, are amenable to PSM. The generality of PSM, in both scope of chemical reactions and range of suitable MOFs, clearly indicates that the approach is broadly applicable. Indeed, the rapid increase in reports on PSM demonstrates this methodology will play an increasingly important role in the development of MOFs for the foreseeable future (117 references).read more

Synthesis of phase-pure interpenetrated MOF-5 and its gas sorption properties.
TL;DR: 1 showed a significantly higher hydrogen capacity (both gravimetric and volumetric) than MOF-5 at 77 K and 1 atm, presumably because of its higher enthalpy of adsorption, which may correlate with its higherVolumetric hydrogen uptake compared to MOF -5 at room temperature, up to 100 bar.

Evaluation of Heterogeneous Metal−Organic Framework Organocatalysts Prepared by Postsynthetic Modification
TL;DR: Several important features of covalent postsynthetic modification (PSM) on MOFs are demonstrated, including facile introduction of catalytic functionality using simple organic reagents (e.g., anhydrides); the ability to utilize and recycle organocatalytic MOFs; and control of catalyst activity through choice of functional group.

Designed Post-Self-Assembly Structural and Functional Modifications of a Truncated Tetrahedron
TL;DR: The post-self-assembly modifications described herein result in three distinct changes to the supramolecular system: an individual building-block component change, an overall structural modification, and a functional evolution of a [6+4] metal-organic supramolescular structure.

TL;DR: Metal-organic framework (MOF-5), a prototype of a new class of porous materials and one that is constructed from octahedral Zn-O-C clusters and benzene links, was used to demonstrate that its three-dimensional porous system can be functionalized with the organic groups and can be expanded with the long molecular struts biphenyl, tetrahydropyrene, pyrene, and terphenyl.
