Judicious choice of framework structure allows for single CO₂ adsorption steps with bulky primary,secondary diamines appended to metal–organic frameworks.

As low as 1% content of a supramolecular catalyst, cucurbit[8]uril, is sufficient to accomplish the photodimerization of Brooker’s merocyanine within 10 minutes.

Catalytic synthesis of substituted 1,2-dihydronaphthalenes via metalloradical activation of o-styryl N-tosyl hydrazones is presented. Substrates with an alkyl substituent on the allylic position reacted to form E-aryl-dienes rather than the expected 1,2-dihydronaphthalenes.

Planar phosphorus(III) centers were effectively stabilized by structural constraint as well as aromatic stabilization in porphyrin-based fused π-conjugated frameworks.

Shuttling rates for neutral and charged [2]rotaxanes with rigid axles varying in lengths from 7.4 to 20.3 Å were found to be independent of the length of the axle, except when the distance was short enough to allow the ring to interact with both recognition sites which provided a short-cut mechanism that significantly lowered the energy barrier.

Self-supporting photo-patterned hybrid gels achieve controlled directional release depending on their surrounding environment.

This paper reports self-assembled multi-component hybrid hydrogels including a range of nanoscale systems and characterizes the extent to which each component maintains its own unique functionality, demonstrating that multi-functionality can be achieved by simply mixing carefully-chosen constituents.

A pair of enantioselective switchable bifunctional catalysts are shown to promote a range of conjugate addition reactions in up to 95 : 5 e.r. and 95% conversion.

A new class of highly luminescent bis(alkynyl)gold(III) N⁁C complexes has been utilized as emissive materials in OLEDs and exhibits mechanochromic behaviors.

We demonstrate that the threaded macrocycles in interlocked porphyrin–corrole conjugates provide a mechanical “picket fence” without affecting their electronic properties.

Switchable crown ether–ammonium [2]rotaxanes with a redox-active tetrathiafulvalene (TTF) unit implemented in their wheels were synthesised and fully characterised.

In-depth experimental and computational ¹²⁹Xe NMR analysis of extraordinarily efficient adsorption of xenon in a porous organic cage.

Transmembrane protein nanopores are shown to be capable of discriminating the supramolecular chirality of cage complexes at the single-molecule level.

Efficient removal of ammonia from air is demonstrated in a series of Brønsted acidic porous polymers under dry and humid conditions. The impact of acidic group strength and their spatial distribution on the ammonia uptake is investigated systematically.

In situ single-crystal X-ray diffraction experiments enable the direct observation of weak metal–gas interactions in a metal–organic framework.

These chiral “synthetic lectins” are the first to discriminate between carbohydrate enantiomers, and also show unprecedented affinities for monosaccharide substrates.

A benzimidazole molecule can be protected from deprotonation with strong base by converting into a suit[1]ane – a type of 3D mechanically interlocked molecule. Utilising a combination of ring-closing and ring-opening metathesis, the wearing of the protective “suit” can be made reversible.

Herein, we have developed a white-light-emitting system based on the formation of discrete lanthanide-based self-assembled complexes using a newly-designed ligand. We demonstrate that fine tuning of the lanthanide ions molar ratio in the self-assemblies combined with the intrinsic blue fluorescence of the ligand allows for the successful emission of pure white light with CIE coordinates of (0.33, 0.34).

We demonstrate a variety of template-directed strategies for preparing linear monodisperse butadiyne-linked porphyrin oligomers by Glaser–Hay coupling, based on the coordination of pyridine-substituted nickel(II) porphyrins to zinc(II) porphyrins.

Oxidative fusion of a meso-phenoxazino Ni(II) porphyrin at high temperature gave a doubly phenoxazine-fused porphyrin as a highly planar diarylamine-fused porphyrin. One-electron oxidation of the corresponding β,β-dichlorinated compound gave a remarkably stable radical cation.

Tuning of the temperature response of perylene bisimide hydrogels exhibiting LCST behavior has been achieved by social self-assembly in water.
