    Host–guest materials open up the possibility of tuning physical properties based on the addition of appropriate guests. Here, a flexible, porous coordination polymer is reported, in which the addition of guest molecules significantly alters the thermal expansion properties as well as deforming the crystal lattice.

    The development of a series of orthogonal binding interactions to direct the controlled self-assembly of mesoscale objects is desirable. Here, the authors use DNA as a sequence-specific glue to assemble hydrogel cuboids into a diverse series of structures in the micro- to millimeter length scale.

    Currently, gold recovery from waste materials requires inorganic cyanides and more environmentally benign methods are required. Here, the authors report that host–guest interactions between α-cyclodextrin and gold lead to the precipitation of one-dimensional superstructures, offering a selective and green alternative.

    A promising route towards molecular devices is the self-assembly of atoms or molecules on a surface. Here, Gruznev et al. show that the synthesis of unique geometries of C60molecules on gold–indium-covered crystalline silicon is governed by moiré interference.

    The fabrication self-sorting supramolecular gels, containing co-existing homomolecular assemblies with similar physical and chemical properties, is challenging. Here pH-controlled self-sorting gelators are reported, where the order of assembly of each component is predetermined by gelator pKa.

    The construction of homochiral surfaces may play a significant role in applications including heterogeneous catalysis and bio-sensors. Here, globally homochiral two-dimensional assemblies of achiral molecules are formed via co-assembly with chiral co-adsorbers, demonstrating a ‘majority rules’ effect.

    Polymer-based actuators, which deform in response to external stimuli, may advance the understanding of biological movement or realization of soft robotics. Here, Harada et al. report a photo-responsive supramolecular hydrogel that displays expansion–contraction abilities owing to host–guest interactions.

    Orthogonal switching has been achieved in supramolecular systems, in which different responses can be triggered on demand by different stimuli. Tian et al.report host–guest heteroternary complexes with both redox- and light-responsive guests in a single, supramolecular entity.

    The spontaneous adsorption of alkanethiols is widely utilized to fabricate functional surfaces but gives limited stability and regularity. Mattiuzziet al. report a method that uses preorganized platforms (rigid tetrapodant calix[4]arenes), which allows further surface functionalization and spatial control.

    The computational prediction of complex protein architectures has been used to design globular proteins, but the folding of collagen triple helices is difficult to predict. Here, a sequence-based scoring function for triple helix is developed and used to select sequences likely to self-assemble with high stability.

    Molecular systems with rigid macrocyclic backbones self-assemble into synthetic nanopores that mimic the mass-transport characteristics of biological channels. Zhouet al. produce self-assembling hydrophobic nanopores that mediate highly selective transmembrane ion transport and highly efficient transmembrane water permeability.

    The crystallization of a racemate on a surface can lead to crystals with a unit cell containing both enantiomers, or to the separation of enantiomers into crystals of single-handedness. This study shows that manganese co-absorbed with a quinone derivative leads to achiral islands, while co-absorption with caesium gives chiral islands.

    Self-assembly of multi-component systems can be used to construct discrete, well-defined, nanoscopic-sized cages. Pasqualeet al. report the self-assembly of conical-shaped carboxylic acid derivatives of calix[4]arene and calix[5]arene, and the uranyl cation UO22+into octahedral and icosahedral anionic metallocages.

    Stimulus-responsive hydrogels have previously been developed that display heat-, light-, pH- or redox-induced sol–gel transitions. Nakahataet al. develop a self-healing supramolecular hydrogel based on host–guest polymers in which redox potential can induce a reversible sol–gel phase transition.

    Hydrogels have a variety of applications including tissue engineering and controlled drug delivery. Here, liquid-crystal hydrogels are developed which transform into a fluid solution upon cooling; cells can be encapsulated in the gel at room temperature, then released at physiological temperatures.

    The construction of porous solids from discrete organic molecules usually involves the formation of regular porous crystals. In this study, a covalent scrambling reaction gives molecules with a range of shapes that do not pack effectively — manipulation of the reagent ratio allows fine control of porosity.

    Cryptophane-A is a prototypical organic host molecule that binds reversibly to neutral guest molecules. Taratulaet al.report X-ray structures of cryptophane-A complexed with a range of host molecules to show that the cryptophane host–guest system exhibits ‘induced fit’.

    The spontaneous ordering of molecules into two-dimensional arrays is usually a result of directional intermolecular interactions. Here, it is shown that electrospray-deposited Mn12(acetate)16forms filamentary aggregates driven by anisotropic interactions, which are a consequence of the complex shape of the molecule.
