The anhydrous proton conductivity of Im@IEF-11 resulting from the integration of imidazole and porous IEF-11 has been investigated, and the highest proton conductive value can reach up to 7.64 × 10−2 S cm−1. Furthermore, IEF-11 is also developed to reduce CO2 due to its reasonable structure and suitable energy band, and its CO formation rate is 31.86 μmol g−1 h−1. [ABSTRACT FROM AUTHOR]

Direct conversion of diluted CO2 to value-added chemical stocks and fuels with solar energy is an energy-saving approach to relieve global warming and realize a carbon-neutral cycle. The exploration of catalysts with both efficient CO2 adsorption and reduction ability is significant to achieving this goal. Metal–organic frameworks (MOFs) are emerging in the field of low-concentration CO2 reduction due to their highly tunable structure, high porosity, abundant active sites and excellent CO2 adsorption capacity. This highlight outlines the advantages of MOFs for low-pressure CO2 adsorption and the strategies to improve the photocatalytic performance of MOF materials at low CO2 concentrations, including the functionalization of organic ligands, regulation of metal nodes and preparation of MOF composites or derivatives. This paper aims to provide possible avenues for the rational design and development of catalysts with the ability to reduce low-concentration CO2 efficiently for practical applications.

A novel polyoxometalate-based metal–organic framework (POMOF) with an ABW network, NENU-601, was synthesized in situ. To the best of our knowledge, this is the first POMOF with a zeolite-like structure, which was designed by regulating the length and angle of mixed ligands and rationally choosing suitable Polyoxometalates (POMs) as nodes.

We have demonstrated for the first time that isostructural homochiral metal–organic frameworks (MOFs) can be synthesized directly from chiral ligands and indirectly from achiral ligands via spontaneous resolution combined with cooperative chirality induction, respectively. Moreover, the usage of different ligands leads to distinct proton conduction behaviors. [ABSTRACT FROM AUTHOR]

An anionic metal–organic framework (MOF) with 1D nanotube channels has been constructed. The charge and size dependent ion-exchange of cationic dyes was investigated. Rho@1 could be used as a dual-emitting fluorescent sensor for sensing explosives by self-referencing energy transfer behaviors. [ABSTRACT FROM AUTHOR]

The structure of a recently-published metal–organic framework is deconstructed into its underlying net which is found to be of exceptional complexity. It is shown that this is because of local pentagonal symmetry and the structure is in fact the simplest possible (minimal transitivity) given that local symmetry. [ABSTRACT FROM AUTHOR]

Three novel self-catenated 4-connected uninodal (65·8)-mok metal–organic rotaxane frameworks (MORFs) containing cucurbit[6]uril were constructed from the in situ trans/cis-configuration (1 : 1) of rotaxanes by taking advantage of a d10 metal ion directed synthesis. It was revealed that the effect of hydrogen bonds and π–π stacking interactions play significant roles in the self-assembly process. [ABSTRACT FROM AUTHOR]

Two S-containing MOFs, interpenetrating IFMC-27 and non-interpenetrating IFMC-28, were synthesized by altering solvent size. The nanoporous IFMC-28 reveals high selective adsorption for Cu2+ ions and has been applied as a chromatographic column for separating transition metal ions for the first time.

The first uninodal 10-connected metal-organic framework, based on pentanuclear cadmium cluster building blocks, exhibits an unprecedented γ-Pu topology, which adds a new member to the series of metal-organic analogues which have a natural materials topology. [ABSTRACT FROM AUTHOR]
