Study of the gas adsorption and thermal and chemical stability of two prototypical members, ZIF-8 and -11, demonstrated their permanent porosity, high thermal stability, and remarkable chemical resistance to boiling alkaline water and organic solvents.
Design and synthesis of an exceptionally stable and highly porous metal-organic framework
Open metal–organic frameworks are widely regarded as promising materials for applications in catalysis, separation, gas storage and molecular recognition. Compared to conventionally used microporous…
Metal-organic frameworks with exceptionally high capacity for storage of carbon dioxide at room temperature.
The various pressures of the isotherm steps correlate with increasing pore size, which indicates potential for gas separations and the amine functionality of the IRMOF-3 pore shows evidence of relatively increased affinity for CO2.
Systematic Design of Pore Size and Functionality in Isoreticular MOFs and Their Application in Methane Storage
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.

This work has shown that highly porous frameworks held together by strong metal–oxygen–carbon bonds and with exceptionally large surface area and capacity for gas storage have been prepared and their pore metrics systematically varied and functionalized.

Covalent organic frameworks (COFs) have been designed and successfully synthesized by condensation reactions of phenyl diboronic acid and hexahydroxytriphenylene to form rigid porous architectures with pore sizes ranging from 7 to 27 angstroms.
Ultrahigh Porosity in Metal-Organic Frameworks
The synthesis of a MOF in which zinc centers are bridged with long, highly conjugated organic linkers, but in which the overall symmetry of the networks created prevents formation of interpenetrating networks is described.
Rod packings and metal-organic frameworks constructed from rod-shaped secondary building units.

The inclusion properties of the most open members are presented as evidence that MOF structures with rod building blocks can indeed be designed to have permanent porosity and rigid architectures.
Hydrogen Storage in Microporous Metal-Organic Frameworks
Inelastic neutron scattering spectroscopy of the rotational transitions of the adsorbed hydrogen molecules indicates the presence of two well-defined binding sites (termed I and II), which are associated with hydrogen binding to zinc and the BDC linker, respectively.
High-Throughput Synthesis of Zeolitic Imidazolate Frameworks and Application to CO2 Capture
Members of a selection of zeolitic imidazolate frameworks have high thermal stability and chemical stability in refluxing organic and aqueous media, and they exhibit unusual selectivity for CO2 capture from CO2/CO mixtures and extraordinary capacity for storing CO2.
