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

TL;DR: It is shown that the transitivity provides a useful method of classifying polyhedra and nets and structures with one kind of edge (edge transitive) are particularly important for design of materials to serve as targets for synthesis.

TL;DR: A wide range of highly active metal NP catalysts for efficient H2 generation from FA under mild conditions were developed, and the size and composition of the NPs can be controlled for the enhancement of catalytic performance for the FA dehydrogenation.

TL;DR: The ability of CD-MOF to separate a wide variety of mixtures, including ethylbenzene from styrene, haloaromatics, terpinenes, pinenes and other chiral compounds is reported, which could lead to cheaper and easier-to-prepare stationary phases for HPLC separations when compared with otherChiral stationary phases, such as CD-bonded silica particles.

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.
