  • Radical polymerizations yield polymers that cannot easily be degraded. The co-polymerization of cyclobutene-based monomers with conventional vinyl monomers has now been shown to result in co-polymers with cyclobutane mechanophores in their backbone, which facilitate on-demand degradation through a combination of mechanical activation and hydrolysis. This approach offers a promising avenue for the degradation of all-carbon-bond-backbone polymers.

  • Most aerial organs of vascular plants are covered by a waxy cuticle that limits water loss. Here the authors show that the asymmetric architecture of the cuticle creates a polarity gradient to ensure directional movement of water through olive and ivy leaf cuticles and construct bioinspired artificial membranes that mimic cuticle behaviour.

  • The ability to heal whilst maintaining original functionality is important for establishing materials with superior longevity. Here, the authors demonstrate a supramolecular polymeric coating which exhibits excellent optical and mechanical properties, even following damage repair.

  • Reversible assembly of supramolecular polymers renders these materials with healing and recycling properties but mechanical properties are often inferior to those of conventional plastics. Here, the authors demonstrate that strong and tough but healable materials can be accessed through the combination of metallosupramolecular polymers with complementary mechanical properties that feature the same metal-ligand complex as binding motif

  • Solid-state organic materials that convert low-power visible light into higher-energy radiation have been synthesized using metal–organic frameworks. This approach could be used to make polymers that increase the efficiency of photovoltaic devices.

  • We introduce a self-assembly strategy that uses the interface of an aqueous two-phase system to template and stabilize molecularly thin biomimetic block copolymer bilayers of scalable area that can exceed 10 cm2 without defects.

  • The latest polymers are chameleon-like: they change colour on deformation. The transduction mechanism underpinning this effect could be used to make polymers that respond in many other ways to mechanical stress.

  • Reduced glomerular filtration rate (eGFR) is a hallmark of chronic kidney disease. Here, Pattaro et al. conduct a meta-analysis to discover several new loci associated with variation in eGFR and find that genes associated with eGFR loci often encode proteins potentially related to kidney development.

  • Functional dyes offer fascinating properties in response to external stimuli and enable unique stimuli-responsive functions in materials by chemical incorporation into polymers. In this review, we highlight our recent studies conducted in the last half decade on stimuli-responsive smart polymers and polymeric materials offering, for example, switchable adhesion, mechanical actuation, and chemical sensing based on functional dyes that are chemically incorporated into the structures, with a particular focus on the stimuli of light, force, electric fields, and chemicals including water.

  • Photoinduced transitions between the solid, glass, and liquid states based on molecular photoswitches promise an enormous variety of applications, such as photoswitchable adhesives, which contribute to material recycling for a sustainable future in the era of composite materials. In this review, we highlight recent progress in the photoinduced transitions of small molecules and polymers and systematically discuss the molecular designs, mechanisms, applications, merits and demerits, and future challenges in each photoswitch and the whole field.
