Cross-linked polymers must maintain physical and chemical properties after recycling to improve sustainability. Here, tuning the curing process to favour a reversible cross-linked network using disulfides and polysulfides bonds retains mechanical performance.

Using an adhesive buffer layer and a high-resolution six-channel inkjet printing system, arrays of stretchable organic electrochemical transistors can be fabricated for application in wearable in-sensor computing platforms.

Multifunctional composites have potential in a number of applications, and it is desirable to have control by external stimuli. Here, the authors report a 4D printing method for liquid crystal elastomer composites with continuous fibres capable of multifunctional actuation.

Reversible photochromic materials offer interesting applications and covalent organic frameworks which photochromic properties are rarely reported. Here, the authors prepare hydrazone-linked covalent organic frameworks with reversible photochromism as anti-counterfeiting inks and optical switches.

Selective encapsulation of molecules within macrocyclic hosts relies on the pore features and nonmacrocyclic crystals for selective molecular encapsulation have yet been challenging. Here, the authors show that planar tris(phenylisoxazolyl)benzene exhibits a porosity without pore behavior and selectively encapsulate cis- over trans-decalin.

Near-infrared transparent films have a number of applications, but combining elimination of UV-vis light and the balance of film thickness and transmittance is challenging. Here, the authors report the development of a thin material with good transmittance and a suitable wavelength cutoff.

High-mobility emissive organic semiconductors integrate efficient charge transport and strong emission features. The development of these materials, which have the potential to overcome performance bottlenecks in organic electroluminescent and photoelectric conversion devices, is opening up new research directions in organic optoelectronics.

An article in Nature Communications introduces the use of acoustic holograms in direct remote printing.

The instability of n-type organic semiconductors in air is a long-standing challenge in organic electronics. Now, a strategy based on the use of vitamin C is developed to stabilize organic semiconductors. Vitamin C scavenges reactive oxygen species and inhibits their generation, improving the performance and stability of organic semiconductors and their electronic devices.

Physical vapour deposition of small-molecule glass formers onto soft substrates enhances the local dynamics at the top free surface, leading to the formation of denser glasses and providing access to states deeper in the potential energy landscape.

An article in Nature Chemistry discovers that the two light-controlled isomers of azobenzene also have very different rupture forces.

Photochromic molecular crystal arrays aligned in the micropores of a polymer membrane show high-performance actuation when stimulated by light. These soft composites might find applications in soft robotic devices.
