Summary: The metal-induced self-assembly strategy promotes the pi-dimerization of viologen-based radicals, forming discrete box-shaped 2:2 macrocycles or coordination polymers. Changing the redox state of the tectons leads to reversible inflation/deflation of the macrocyclic assemblies, with viologen-centered electron transfer triggering dissociation of coordination polymers. The driving force of the disassembling process is the formation of stabilized 2:2 assemblies through pi-dimerization of viologen cation radicals.

Summary: This article presents an alternative method for preparing nitrones using a tetrahedral capsule as a nanoreactor in water. The hydrophobic cavity of the capsule was utilized to reduce reaction times and facilitate the separation of nitrones from the reaction mixture, resulting in comparable yields to existing methods. The method is based on an eco-friendly approach and can be extended to the synthesis of other substrates using various types of macrocyclic hosts commonly used in supramolecular chemistry.

Summary: Miktoarm star polymers are a type of branched polymers with a star-shaped architecture based on different assembly properties. The synthesis of these polymers can be challenging, especially when using covalent strategies to link different polymers. This study presents an approach using orthogonal metal-ligand interactions to connect the building blocks and create miktoarm topology. The structures obtained are investigated using diffusion-ordered nuclear magnetic resonance spectroscopy, analytical ultracentrifugation, and dynamic light scattering.

Summary: This study demonstrates the formation of novel supramolecular miktoarm star copolymers with a zinc phthalocyanine (ZnPc) core using metal-ligand coordination interactions. Various linear polymers with pyridyl end groups are prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization, which facilitates coordination to the ZnPc core of 4-armed star-shaped polystyrene prepared via atom-transfer radical polymerization (ATRP). The concept of supramolecular complexation can be extended to the preparation of AB(4)-type supramolecular miktoarm star-shaped copolymers with functional cores.

Summary: In this study, the interaction between a star block copolymer T1304 and the biologically important additive, bile salts, in aqueous solution was investigated. The mixed micelles of T1304-BS were characterized using various techniques such as cloud point, scattering, and spectral analysis. The solubilization of the drug Quercetin in the mixed micellar environment was also studied. It was found that the addition of bile salts led to an increase in cloud point and a decrease in micellar size. NaDC showed the highest degree of replacement of T1304 molecule in the mixed micelles due to its lower critical micelle concentration and higher hydrophobicity.

Summary: Recent studies have introduced a new generation of photoinitiators for 3D laser nanoprinting, replacing two-photon absorption with two-step absorption. This can now be achieved using inexpensive blue laser diodes instead of expensive femtosecond laser systems. Additionally, researchers are exploring alternative photoinitiators that can be excited by one-color two-step absorption and be de-excited by a different laser color.

Summary: It is shown that the postfunctionalization of solid polymeric microspheres can produce fully and extensively functionalized materials instead of core-shell structures. The complete functionalization is exemplified by photochemically generated microspheres, which are subsequently converted into polyradical systems. By directly visualizing the chemical distribution inside the postfunctionalized microspheres using characteristic electron energy loss signals in transmission electron microscopy (TEM), this study pioneers characterization methods with high sensitivity and resolution for all-organic low-contrast soft-matter material structures. The successful combination of ultrasonic ultramicrotomy and electron energy loss spectroscopy (EELS) and electron spectroscopic imaging (ESI) in TEM opens up a new avenue for analyzing such structures.

Summary: We present a single-chain nanoparticle (SCNP) system that exhibits three times higher catalytic efficiency for the photooxidation of nonpolar alkenes compared to an equivalent concentration of small-molecule photosensitizer. The SCNP is constructed using poly(ethylene glycol) methyl ether methacrylate and glycidyl methacrylate, compacted through multifunctional thiol-epoxide ligation, and functionalized with Rose Bengal (RB). The confined RB within the SCNP achieves enhanced photocatalysis for nonpolar alkenes due to spatial proximity in the hydrophobic region.

Summary: Independently addressing photoreactive sites within one molecule with two colours of light is a daunting task. In this study, we combine two sequence independent and λ-orthogonal chromophores in one heterotelechelic dilinker molecule, utilizing the same reaction partner, a maleimide-containing polymer, to exploit their distinct reactivity. We demonstrate that polymer network formation can only occur when two colours of light are employed. Linker-decorated post-functionalized polymers are generated at either wavelength and in either sequence upon single colour irradiation. However, network formation is achieved only through sequential or simultaneous irradiation with two colours of light. The introduced photoreactive system highlights the power of wavelength orthogonal chemistry in macromolecular synthesis.

Summary: This study demonstrates the power of photochemical action plots in understanding the wavelength-resolved photochemistry of two triazolinedione (TAD) substrates. Despite having similar absorption spectra, the TAD substrates exhibit vastly different photoreactivity. By designing a 'hybrid' bisfunctional TAD molecule, the exceptional and site-selective (photo)chemical behavior of both substrates is demonstrated within a single small molecule.

Summary: The molecular network connectivity in dynamic polymer networks significantly affects material properties and reprocessing conditions. The influence of regioisomerism in light-stabilized dynamic materials has been highlighted. Interchanging regioisomer fractions of substituted naphthalenes with triazolinediones (TADs) in a photo-driven cycloaddition reaction has been demonstrated to affect the cycloreversion kinetics and is important for the design of dynamic covalent materials. The development of completely regioselective TAD/naphthalene systems and the control of cycloreversion kinetics through naphthalene substitution offer new opportunities for the advancement and applications of light-stabilized dynamic materials.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study focuses on the development of high-performance, low-migration photoinitiators. A polymerizable photoinitiator (VBP) was synthesized by introducing an ethylene group into benzophenone, and three different molecular weight single-component photoinitiators (PVBN1-3) were synthesized based on VBP. The results show that these new photoinitiators have stronger absorption ability compared to benzophenone and significantly reduce the migration of initiators and co-initiators, addressing the safety concerns caused by migration.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.
