Summary: The future of materials chemistry lies in precisely arranging components with larger dimensions and more complex compositions. Dynamic covalent nanoparticles are emerging as attractive nanosized building blocks that allow for controlled assembly and composition. By understanding the underlying molecular events and using kinetic models, selectivity and composition of the materials can be optimized.

Summary: Cyclophanes are compounds with unique properties, but their synthesis can be challenging. This study presents a metalloid-directed self-assembly method for synthesizing disulfide and thioether assemblies, and demonstrates its applicability to macrocycles and diverse cage structures.

Summary: In this study, ditopic ligands incorporating various functional groups were self-assembled with Pd(ii) or Pt(ii) complexes, leading to the formation of metallacycles. The shape and nuclearity of the metallacycles were controlled through concentration changes and the addition of aromatic guests or other external stimuli.

Summary: This study reported the synthesis and characterization of homochiral macrocycles, using 1,1'-bi-2-naphthol (Binol) units as chirality inducers and pyridyl units for the assembly of helical nanostructures upon coordination with Pd(II) metal ions. CD and NMR spectroscopies confirmed the formation of ordered 1D assembly in solution, while AFM studies showed the capability of the molecular systems to form nanoscale structures. The transfer of chiral information led to the formation of helical nanofibers with specific dimensions.

Summary: This work systematically studied the design of stable imine bonds in amphiphilic micellar structures, considering parameters such as pH, concentration, and the positioning of the imine function. The stable systems were shown to be stimuli-responsive, potentially useful for trapping and releasing micellar components as needed.

Summary: Self-assembled nanotubes with distinct internal arrangements and properties are achieved through different supramolecular scenarios prior to polymerization, driven by chelate cooperativity and self-recognition motifs at the edges. The chosen supramolecular pathway for structurally related molecules with complementary nucleobases is determined by their propensity for specific cyclic structures through Watson-Crick pairing. These findings provide insight into the unpredictability and experimental evaluation of self-assembly pathways, as well as the design of functional nanomaterials with controlled helicity and chiroptical properties.

Summary: Dynamic control over molecular emission is achieved through time-encoded locking and unlocking of individual vibrational emissive units, allowing for the development of dynamic multicolor fluorescent systems. The emission wavelength and lifetime can be readily controlled by adding chemical fuels, providing a robust and versatile way to modulate multi-color molecular emission in a time-dependent manner.

Summary: This study reports on the dynamic covalent self-assembly of anion cryptates that offer an inherent mechanism for the release of guest ions. These self-assembled architectures exhibit moderate affinity for anions such as chloride, bromide or iodide, making them suitable for membrane transport applications.

Summary: The confinement-mediated self-assembly of colloidal crystals in dynamic borate ester-based networks was demonstrated to produce spherical opal composites using a microfluidic device. The resulting optical beads are flowable and injectable, facilitating injection molding of three-dimensional well-defined macroscopic opals. Furthermore, the opal composites formed in semi-spherical sessile microdroplets can serve as individual pixels for two-dimensional patterns integrating angle-independent structural colors and self-healing characteristics.

Summary: This study demonstrates the use of visible light to shift dynamic covalent imine assemblies out of equilibrium. A fluorinated azobenzene building block was combined with different amines to create a library of imine macrocycles. The chiral amine provides access to a rich network of macrocycles that undergo isomerisation and interconversion between different species.

Summary: The synthesis of helically chiral macrocycles composed of dibenzo[5]helicene units and trans-stilbene-4,4'-diyl linkers is reported. Different stereoisomers of these macrocycles were obtained through chiral resolution. The self-assembly of these macrocycles into long 1D molecular stripes in ordered 2D nanocrystals was studied using AFM.

Summary: Golgi apparatus-targeted nano-mechanical disruption is an attractive approach for killing cancer cells by multimodal mechanism and avoiding drug resistance. The transformable peptide C6RVRRF4KY can self-assemble into nontoxic nanoparticles in aqueous medium but transformed into left-handed helical fibrils (L-HFs) after targeting and furin cleavage in the Golgi apparatus of cancer cells, leading to mechanical disruption and death of cancer cells without acquired drug resistance. This nanomechanical disruption concept should also be applicable to multidrug-resistant bacteria and viruses.

Summary: SuFEx is a type of click chemistry that allows covalent linking of modular units through sulfur(vi) connective hubs, leading to the synthesis of structurally diverse copolymers with high efficiency and stable bonds. SuFEx click chemistry offers the potential for post-polymerization modification, enabling the synthesis of materials with control over composition and conformation, making it a powerful tool in polymer chemistry.
