Summary: Wearable devices can benefit from the use of stretchable conjugated polymers (CPs). Traditional design assumes that low elastic modulus (E) is crucial for achieving high stretchability, but this research challenges this notion. It is discovered that the degree of entanglement, rather than softness alone, determines stretchability. Even rigid CPs can exhibit high stretchability. Two model CPs with different elastic moduli are studied to further investigate mechanical behavior and deformation mechanisms. By challenging the conventional design metric of low E for high stretchability and highlighting the importance of entanglement, this research hopes to expand the range of CPs available for use in wearable devices.

Summary: Conjugated polymers often have both crystallized and amorphous regions in the solid state, making it challenging to accurately determine their precise microstructures. This study obtained crystals of two typical conjugated polymers through a controlled self-assembly process, allowing for the determination of crystal structures using X-ray techniques and molecular simulations. The highly oriented polymer chains in the crystals exhibit higher mobilities and lower hopping energy barriers compared to spin-coated thin films.

Summary: This study reports wide bandgap polymers based on 5,6-difluorobenzo[c][1,2,5]oxadiazole (ffBX) for non-fullerene organic solar cells. The solubility, solid state packing, and bulk-heterojunction morphology of the polymers are finely tuned through side chain engineering. Encouragingly, a decent efficiency of 14.25% is achieved with the polymer Oc25 blended with the non-fullerene acceptor Y6.

Summary: In this study, we demonstrate the synthesis of surface-grafted D-A polymer brushes by alternating attachment of tailored monomers. The structure and properties of the brushes can be controlled by different coupling reactions, such as Sonogashira, Stille, and Huisgen cycloaddition. The D-A brushes exhibit reduced bandgaps, semiconducting properties, and the ability to form aggregates.

Summary: Modern implantable medical devices have advanced beyond being mere substitutes, to actively participating in restoring bodily functions. The use of polymers in biomedical applications is attractive, but single homopolymers often fall short in meeting all desired characteristics, leading to the introduction of polymer blending and composites to overcome these limitations.

Summary: This article describes a design strategy for electronic materials using conducting polymers that can dynamically adapt to deformation rates. By utilizing interconnected nanoscopic core-shell micelles, the shells retain material integrity under strain while the cores control the extent of elongation, adapting to deformation rates. A prototype based on polyaniline showed significant increases in ultimate elongation and toughness at increasing deformation rates. This concept can be applied to create self-protective soft electronic materials with enhanced durability.

Summary: Contamination of per- and polyfluoroalkyl substances (PFAS) in water supplies has serious health and environmental consequences. However, there are few suitable and rapid on-site methods for monitoring PFAS concentrations. In this study, a novel and rapid method for detecting perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) was developed using the differential behaviors of PFAS at interfaces. The method is based on the measurement of surface and interfacial tensions, which revealed that PFAS preferentially assemble at the water-fluorocarbon oil interface. The change in fluorescence emission intensity correlated with the concentrations of PFAS, demonstrating the potential for on-site PFAS detection.

Summary: This study presents the application of amphiphilic block copolymer surfactants in sensing devices. The composition and molecular weight of the surfactants were found to affect their interfacial properties, and conformational changes of the polymers led to variations in interfacial tension reductions. By modifying the surfactants with trypsin, its functionality was retained. The modified surfactants were successfully used in an active complex emulsion framework, which allowed for control of functionality through shielding of active compounds.

Summary: The increasing contamination in potable water supplies requires the development of sensing methods that provide speed and selectivity for safety. One promising method relies on recognition and detection at the liquid-liquid interface of dynamic complex emulsions. By modifying the liquid-liquid interface, the synthesis and characterization of block copolymers have been reported, which can selectively measure the concentrations of dissolved metal ions, thus providing a platform for detecting safety in a complex environment.

Summary: In this study, we demonstrated a real-time optical sensing platform using poly(dimethylsiloxane) (PDMS) microfluidics and complex droplets as sensing materials. Changes in interfacial tension were transduced into optical signals through a mechanism called directional emission. By varying the interfacial functionalization and fluorescent dye with characteristic wavelength, we generated multiple formulations of droplets and obtained differential responses to stimuli that alter interfacial tensions (i.e., composition of surfactants, pH).

Summary: The development of sensing methods that provide speed and selectivity is necessary to address the increasing contamination in potable water supplies. One promising method involves recognition and detection at the liquid-liquid interface. This method transduces changes in interfacial tensions into optical signals, providing selectivity. In this study, amphiphilic block copolymers modified with metal chelators were synthesized and characterized for the selective measurement of dissolved metal ions. Significant reduction in interfacial tensions and increased surface excess and surfactant effectiveness were observed when the block copolymers were complexed with metal ions. The researchers also demonstrated selective detection of iron(III) cations in complex matrices of synthetic groundwater, even in the presence of interference from other cations.
