The realisation of permanent microporosity in liquids transforms the way functional porosity may be implemented. Considering recent advances, we explore the developing theory of porous liquids and delve into the discovery process and applications.

Mechanically interlocked molecules that employ a handcuff component provide a pathway to highly unusual structures, a new nomenclature is proposed which helps to identify opportunities for employing this structural unit for new architectures.

Catenane chemistry is closely associated with that of rotaxane and knot, and this perspective highlights their similarities and differences in various aspects including synthesis, structure and properties.

The self-assembly of molecules in two dimensions (2D) is gathering attention from all disciplines across the chemical sciences. This perspective discusses the main strategies to direct the supramolecular self-assembly of organic monomers in 2D.

Purely organic room temperature phosphorescence, especially in aqueous solution, is attracting increasing attention owing to its large Stokes shift, long lifetime, low preparation cost, low toxicity, good processing performance advantages, and broad application value.

On–off competitive inhibition is presented. Photoswitchable pseudorotaxane controls the rate of self-reaction and product selectivity of external reactions.

Cuboctahedral [Pd₁₂L₂₄]²⁴⁺ cages based on low-symmetry ligands can potentially form a vast number of isomers, but the self-assembly process was found to be highly selective.

The emissive features of supramolecular polymers formed by cyano-luminogens depends on the nature of the central aromatic unit. Intramolecular H-bonded species influence the chiroptical properties and the resulting aggregated species can be kinetically controlled.

Chemically fueled supramolecular materials offer unique properties like the ability to self-heal, yet, mechanisms remain elusive. Here, we demonstrate that chemically fueled gels heal because of a molecular glue-based mechanism.

Encapsulation of guests in metal–organic cages allows control over chemical reactivity. Focusing on the hydrolysis of amides, here we show an effective molecular simulation approach to reconstruct reactivity in host–guest systems in dynamic regimes.

A combination of computational and synthetic phospholipid vesicle/nanodisc assays are used to investigate the mode of action for a class of antimicrobial agents, while a range of DMPK studies establish agent druggability.

The rippled sheet was proposed by Pauling and Corey in 1953, yet structural foundation remains extremely limited. Here we report on three X-ray crystal structures of rippled β-sheets, thus providing the long-sought structural basis for the field.

Here we report that the open large cavity of an M₂L₄ polyaromatic cage can efficiently bind sterically demanding organic dyes with coumarin, perylene bisimide, and porphyrin cores in aqueous solution. The spectroscopic properties of the caged dyes are largely modulated in the cavity.

Green luminescent microspheres, generated via charge-transfer interaction-induced hierarchical co-assembly of a bis-naphthyl dipicolinic amide derivative and tetracyanobenzene, transfer energy to long-wave emitting dye.

A supramolecular strategy is reported for converting the conventional photodynamic agents from a singlet oxygen generator to a superoxide radical generator by the host–guest interaction enhanced electron transfer.

Readily obtained pillar[5]arenes with pure planar chirality enabled CPL on/off control of an assembled system by varying the feed ratio.

Multiple metastable doubly threaded [3]rotaxanes using a large 46 atom ring were prepared and fully characterized. Varying the stopper group size gave a range of interlocked stabilities in CDCl₃ from a half-life of <1 minute to ca. 6 months.

The selective synthesis of three kinds of supermolecular topologies, molecular Borromean ring, [2]catenane and metallarectangle based on two alkynyl ligands is presented. Remarkably, the NIR photothermal conversion efficiency was found to improve as the π–π stacking increases.

We apply an allyl acetate fuelled chemical reaction network (CRN) to control the coacervation of macromolecular species at constant physiological pH without the need for complex biomolecules.

The selective binding of anions transform macrocycles into amphiphiles that form monolayers on the surface of water depending upon the relative roles of anion hydration and anion recognition.

A molecular folding strategy is developed to construct ferrocenyl diamino acid conjugated polyhedral oligosiloxane molecules. Hydrogen bonding-driven folding facilitates the chirality transfer from the molecular scale to the micrometer scale.

Self-inhibitory feedback regulated transient assembly of a CB[8] based nanozyme is reported whose lifetime can be manipulated in multiple ways, ranging from minutes to hours.

We present two new europium-based anion receptors that selectively bind to inorganic phosphate and AMP in aqueous media. Their sensing selectivity follows the order AMP > ADP > ATP, representing a reversal of the selectivity order observed for most nucleoside phosphate receptors.

Chiral self-sorting supramolecular polymerization of bola-type terpyridine-based ligands (R-L¹ and S-L¹) comprising R- or S-alanine analogs occurred upon addition of Ag⁺ in one enantiomeric component.

A covalent organic framework (Tp-PTO-COF) with carbonyl active sites was proposed as a novel cathode material and successfully applied in aqueous rechargeable zinc-ion batteries (ZIBs).

Arene–perfluoroarene interactions resulted in enhanced crystallinity between analogous perhydro- and perfluoro macrocycles in a supramolecular nanotube assembly.

Alkyl chain compression of alkanediphosphate guests was achieved by head-to-head cyclodextrin [3]pseudorotaxanes in a mechanostereoselective self-assembly process.

A new oxanorbornene-fused nanobox encapsulated C₇₀ selectively in solution with a binding constant of (3.2 ± 0.1) × 10⁶ M⁻¹. Reductive aromatization of this nanobox led to observation of a new zigzag carbon nanobelt by mass spectroscopy.

Coordination Sphere Engineering (CSE) allows non-statistical assembly of heteroleptic supramolecular architectures by fine adjustment of steric and electronic features around square-planar Pd(II) cations with naphthyridine donors.

An enhanced N-directed electrophilic C–H borylation methodology has been developed that provides access to azaborine containing helicenes.
