  • Mesoporous polymeric materials are good candidates for advanced separation materials, though their low-cost production remains challenging. Here, the authors report a microphase separation technique for the fabrication of nanoporous networks from frozen solutions of common polymers.

  • Polymeric impurities in liquid crystals are known to perturb liquid-crystalline order. It is now shown that spatial gradients in the order, created by illuminating the materials with ultraviolet light, can be used to generate forces that allow the polymers to be concentrated or dispersed in the liquid crystal.

  • Self-organization that occurs far from thermodynamic equilibrium is ubiquitous in nature but has remained challenging to control in synthetic supramolecular systems. A complex system has now been devised that displays such behaviour. Porphyrin derivative monomers undergo living supramolecular polymerization, a reaction underpinned by the interplay of two supramolecular polymerization pathways.
