Selective nitrogen adsorption via backbonding in a metal–organic framework with exposed vanadium sites
Nitrogenases use transition metals to selectively capture weak π acids such as N2 by employing backbonding interactions. Here, a metal–organic framework with exposed vanadium sites is presented that uses this approach for selective capture of N2 from CH4, with impressive selectivity and capacity.

Quantitative production of butenes from biomass-derived γ-valerolactone catalysed by hetero-atomic MFI zeolite
Production of olefins from biomass-derived γ-valerolactone could lead to sustainable chemical processes, but catalysts suffer from deactivation due to water. Here, a MFI-type zeolite doped with Nb(v) and Al(iii) shows >99% yield at 320 °C and catalyst stability over 180 hours.

Highly stable fullerene-based porous molecular crystals with open metal sites
Porous molecular crystals are easy to fabricate but thought to have limited stability as they are bound by non-covalent interactions. Here, a porous crystal composed of C60 and phthalocyanine is demonstrated with stability to heat, acid, base and high pressures.

Ordered polymeric membranes using metals
By combining metal ions, organic linkers and polymers, ordered frameworks with controlled crystallite size can form. When fabricated into membranes, they combine superlative CO2/N2 separation properties with good hydrolytic stability.

Reversible adsorption of nitrogen dioxide within a robust porous metal–organic framework
High and reversible nitrogen dioxide (NO2) uptake, and low-concentration NO2 removal from gas mixtures, is observed in a metal–organic framework. The NO2 is bound within the pores by cooperative supramolecular interactions.

Liquid metal–organic frameworks
The structure and porosity of a zinc imidazolate framework above the melting point was studied with neutron and X-ray scattering, and molecular dynamics. The porosity and local bonding of the framework persist even in the liquid phase.

Fast and long-range triplet exciton diffusion in metal–organic frameworks for photon upconversion at ultralow excitation power
Controlled overlap of molecular orbitals in metal–organic frameworks enhances triplet exciton diffusion in these structures, which are now used in solid-state photon upconverters operating under excitation power comparable to solar irradiance.
