    We report a strategy that yields thermally and hydrothermally stable silicates by expansion of a one-dimensional silicate chain with an intercalated silylating agent that separates and connects the chains.

    A route to greatly elevate joint densities of states by introducing a flat-band electronic structure is demonstrated, showing metallic λ-Ti3O5 powders have a high solar absorptivity and offering insights into access to cost-effective solar-to-steam generation.

    Selectively functionalized macrocycles were synthesized with reactivities that preferentially aligned to create well-defined pores across an ultrathin nanofilm offering a strategy to create subnanometre channels in polymer membranes, and demonstrating potential for accurate molecular separations.

    Using integrated differential phase contrast scanning transmission electron microscopy, the atomic imaging of single pyridine and thiophene molecules identifies host–guest interactions in zeolite ZSM-5 and their adsorption and desorption behaviours can be studied.

    A metal–organic framework membrane based on fumarate and mesaconate linkers is shown to have a pore aperture shape that enables efficient and cost-effective removal of nitrogen and carbon dioxide from methane.

    A protocol in which monomers are pre-organized using a reversible and removable urea linkage enables the production of covalent organic frameworks with higher crystallinity and porosity than those produced using standard approaches with randomly aligned monomers.

    The orientation of a rotating para-xylene molecule in the nanochannel of a zeolite framework can be visualised by electron microscopy to determine the host–guest van der Waals interaction inside the channel.

    A diversity-oriented synthesis approach that yields a library of architecturally broad microporous polymers is used to develop structurally diverse polymer membranes with ion specificity and to screen their properties.

    A direct ink writing protocol for silica aerogels enables 3D printing of lightweight, miniaturized objects with complex shapes, with the possibility to easily add functionality by incorporating nanoparticles.

    Energy–structure–function maps that describe the possible structures and properties of molecular crystals are developed, and these maps are used to guide the experimental discovery of porous materials with specific functions.

    Two flexible metal-organic frameworks are presented as solid adsorbents for methane that undergo reversible phase transitions at specific methane pressures, enabling greater storage capacities of usable methane than have been achieved previously, while also providing internal heat management of the system.

    A series of porous crystalline materials known as metal–organic materials are prepared, and a full sorption study shows that controlled pore size (rather than large surface area) coupled with appropriate chemistry lead to materials exhibiting fast and highly selective CO2 sorption.

    Many naturally occurring substances have a 'handedness' that enables them to interact highly specifically with matter or light. The helical features responsible for this can now be replicated in solid, porous films. See Letter p.422

    Some beetle shells exhibit iridescence owing to the chiral organization of chitin making up the beetle's exoskeleton. Inspired by this, these authors fabricate thin glass films with helical pores introduced using a renewable cellulose template. The chiral structure allows the material, which can be free-standing, to selectively reflect light at a specific wavelength that can be tuned across the visible spectrum by altering the ratio of silica to cellulose during synthesis.
