TLDR
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.Abstract:
The long-standing challenge of designing and constructing new crystalline solid-state materials from molecular building blocks is just beginning to be addressed with success. A conceptual approach that requires the use of secondary building units to direct the assembly of ordered frameworks epitomizes this process: we call this approach reticular synthesis. This chemistry has yielded materials designed to have predetermined structures, compositions and properties. In particular, 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.read more

High and selective CO2 capture by two mesoporous acylamide-functionalized rht-type metal–organic frameworks
TL;DR: Two mesoporous and flexible acylamide-functionalized rht-type MOFs exhibit not only high excess unsaturation CO(2) uptake at 20 bar and 273 K, but also good selectivity of CO( 2)/CH(4) andCO(2)/N(2), confirmed by GCMC and first-principles calculations.

TL;DR: It was demonstrated that iodine migration in the solid mixture was triggered by the spin transition of 1-I, and the magnetically bistable porous framework decorating guest interactive open-metal-site in the pore surface makes it possible to modulate T(c) ad arbitrium through unique postsynthetic method using iodine migration.

Selecting metal organic frameworks as enabling materials in mixed matrix membranes for high efficiency natural gas purification
Seda Keskin,David S. Sholl +1 more
TL;DR: In this paper, the authors examined the challenge of selecting metal organic frameworks (MOFs) for use in high performance mixed matrix membranes using a combination of atomistic and continuum modeling and identified a highly selective MOF that is predicted to greatly enhance the performance of Matrimid and a range of other polymers for CO2/CH4 separations.

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.
