Multifunctional metal–organic frameworks constructed from meta-benzenedicarboxylate units

Abstract

Metal-organic frameworks (MOFs), also known as porous coordination polymers (PCPs), are an emerging type of porous materials which are formed by the self-assembly of metallic centers and bridging organic linkers. Design and synthesis of organic linkers are very critical to target MOFs with desired structures and properties. In this review, we summarize and highlight the recent development of porous MOFs that are constructed from the multicarboxylate ligands containing m-benzenedicarboxylate moieties, and their promising applications in gas storage and separation, heterogeneous catalysis and luminescent sensing.

A stable metal–organic framework with suitable pore sizes and rich uncoordinated nitrogen atoms on the internal surface of micropores for highly efficient CO2 capture

“…[19][20][21][22] The focus on exploiting their high surface areas and large pore size conventionally are far from enough. To date, various feasibility strategies, such as the introduction of a high density of open metal sites, charged skeleton of MOFs, and decoration with polar substituent groups (for instance, -COOH, -NH 2 , -OH), have been explored to enforce their interactions and thus enhance the adsorption capacity and selectivity of MOFs toward CO 2 .…”

Network Topology

“…Interestingly, in cases of (planar) hexatopic linkers, they were never considered as a single 6-c node. Many more enlightening examples for the relationship between nets, which are derived by splitting n-topic linkers into more than one n-coordinated vertex, can be found in [9,14,49]. These aspects are also of considerable importance for future linker and MOF design.…”

Nets, tiles, and metal-organic frameworks

“…Most do indeed have nbo-derived nets of minimal transitivity, but of three distinct topologies (fof, fog, tfb), although the authors of the compounds in question generally do not recognize this. 4,24 It is interesting that the binodal edge-transitive 4-c nets, ssa and ssb, 19 have only been found in MOFs with tetratopic linkers and derived nets with transitivity 2 2 sty (from ssa) and stu and stx (from ssb). 4 This work was supported by the U.S. National Science Foundation, Grant No.…”
