Carving up COFs

The stacking of layered COFs featuring crown ether hosts can be disrupted by adding cationic guests, enabling the exfoliation of these materials into well-defined sheets.

    Metabolic labelling with unnatural sugars can be used to selectively label tumours with chemical tags. These tags then enable the targeted delivery of molecular cargo including diagnostic and therapeutic agents. This Review Article discusses progress in the design and delivery of unnatural sugars for metabolic labelling of tumour cells and the subsequent development of tumour-targeted chemistry.

    Artificial systems capable of photocatalytic hydrogen production are not typically based on precisely controlled scaffolds. Now, statistical seeded crystallization of block copolymers—bearing either a pendant cobalt catalyst or a photosensitizer—from solution has been shown to yield recyclable, colloidally stable nanofibres that can be tailored to promote photocatalytic hydrogen production from water.

    The self-assembly of haemoglobin-containing erythrocyte membrane fragments onto the surface of preformed coacervates has been used to make hybrid synthetic cells that can initiate nitric-oxide-induced vasodilation. These synthetic cells encapsulate enzymes that generate a flux of nitric oxide, as well as exhibiting high haemocompatibility and increased blood circulation times.

    The majority of discrete structures obtained by self-assembly possess high symmetry, and thus low complexity: all subunits relate to their neighbours in a similar manner. Now, the spontaneous formation of complex low-symmetry assemblies produced from a single building block has been demonstrated using a systems chemistry approach. The single building block oligomerizes to form specific homomeric cyclic macromolecules that adopt a folded conformation.

    Interactions that generate directed movement in response to a chemical stimulus occur in nature but have been difficult to realize in synthetic systems. Now, it has been shown that asymmetric micelle-mediated exchange of haloalkanes can be used to create tunable chasing interactions between chemically distinct microdroplets. Collective interactions lead to the formation of droplet assemblies with emergent self-organization and collective behaviours.

    Nature successfully uses supramolecular assemblies for efficient and robust solar energy harvesting; however, mimicking such material systems for applications in optoelectronic devices has been hampered by stability issues such as the fragility of the supramolecular structures used and the delicate nature of Frenkel excitons. Now, enabled by tunable cage-like scaffolds, stable supramolecular light-harvesting nanotubes have been composed that are robust even under heat stress.

    As a consequence of their high instability, main-group carbonyl complexes are rare — only a few have been detected, typically in low-temperature matrices. Now, two siliconcarbonyl complexes have been isolated using innovative substituent patterns at the Si centre; their reactivity resembles that of their transition-metal counterparts.

    Artificial photosynthesis represents a promising method of generating hydrogen for our clean and sustainable energy needs. Now, photocatalytic nanofibres have been developed that incorporate photosensitizers and catalysts into well-defined self-assembled structures for efficient hydrogen production.

    Interactions between two bodies that are both attractive and repulsive — such as predators chasing prey — are common in nature. Similar chasing behaviour has now been engineered in self-propelling microdroplets and controlled through fundamental physical and chemical mechanisms.

    It is far from certain how simple chemical reactions became interconnected networks that gave rise to life on early Earth. Exploring the possible ways in which this could have occurred is an active area of research and a collection of articles in this issue consider what chemical steps may have been taken on the path towards life as we know it today.
