Substituent effects on through-space intervalence charge transfer in cofacial metal–organic frameworks

Using a combined experimental, theoretical and density functional theory analysis, important insights into the effects of structural modifications on the degree of electronic coupling and rate of electron transfer are obtained for the framework [Zn(BPPFTzTz)(tdc)]·2DMF.

‘Eye’ of the molecule—a viewpoint

MOF-711 is constructed from zirconium oxide SBUs and benzenedicarboxylate linkers. Rotational distortion differentiates the Zr ions into three types. We show the complexity of these crystals, which are best described from the ‘eye’ of the molecule.

Improved photodegradation of anionic dyes using a complex graphitic carbon nitride and iron-based metal–organic framework material

The heterojunction between a metal–organic framework and graphitic carbon nitride can form a novel porous structure which reduces the rate of electron–hole recombination, thus improving the photocatalytic performance of the composite for wastewater treatment.

Monolithic metal–organic frameworks for carbon dioxide separation

The use of metal–organic frameworks (MOFs) in industry has been limited due to a lack of shaping technologies. Monolithic MOFs (monoMOFs) offer a viable alternative to traditional shaping offering high density materials for adsorption processes.

Effect of linker functionalisation on the catalytic properties of Cu nanoclusters embedded in MOFs in direct CO and CO2 reduction by H2

We investigated the performance of Cu nanoclusters in Zr-MOF pores towards direct CO2 reduction as a function of linker. We found no evidence of electronic promotion but we showed that higher inorganic node acidity favours longer-chain products.

About this collection

We are delighted to share with you a selection of the papers associated with a Faraday Discussion on MOFs for energy and environmental applications. More information about the event may be found here: http://rsc.li/mofs-fd2021. Additional articles will be added to the collection as they are published. The final versions of all the articles presented and a record of the discussions will be published after the event.

The area of MOFs and related materials is arguably one of the hottest interdisciplinary subjects spanning chemistry, materials science, physics and engineering. A primary reason for this major interest is the possibility of tuning the chemical and structural flexibility of these materials using an enormous variety of combinations of metal ions, bridging ligands, counter-ions and formation of hybrids and composites.
