Summary: The combination of multiple orthogonal interactions enables hierarchical complexity in self-assembled nanoscale materials. This study demonstrates the efficient supramolecular polymerization of DNA origami nanostructures using a multivalent display of small molecule host-guest interactions, and exploits high-affinity CB[7]-adamantane interactions to enable responsive enzymatic actuation.

Summary: The present study focuses on the supramolecular host-guest complexation of OCASP into b-CD, resulting in a thermoresponsive nanotubular architecture. The inclusion complex was characterized using various techniques, and the formation of nanotubes was observed. The reversible switching of assembly and disassembly of the system was demonstrated by temperature changes. Hydrophobic interactions were identified as the main driving force behind the hierarchical structure formation, as confirmed by control experiments. Molecular dynamics simulations further elucidated the stepwise formation process of this hierarchy. This stimuli-responsive system has the potential to tailor its physical properties and contribute to the fabrication of novel smart materials.

Summary: Entropy compartmentalization provides new self-assembly routes to colloidal host-guest structures. By modifying the shape of guest particles, a variety of crystal structures and pore motifs can be formed when mixed with star-shaped host particles. The assembly is driven by entropy compartmentalization, with different contributions from the host and guest particles to the free energy of the system.

Summary: Entropy compartmentalization provides a new self-assembly route for colloidal host-guest (HG) structures. Leveraging host particle shape has been recently proposed and demonstrated for the assembly of HG structures. However, the influence of guest particles on the porous network structure of host particles has not been explored.

Summary: The study developed a novel nanohybrid shear-thinning hydrogel with fast gelation and variable mechanical and biological properties through self-assembly and crosslinking processes. By controlling macromere concentration and host-guest ratio, the rheological and mechanical properties of hydrogels can be modulated, affecting crosslinking density and network structure. The designed nanohybrid hydrogel exhibited excellent durability and biocompatibility based on the specified parameters.

Summary: Chiral materials, particularly cyclodextrins, have gained attention in recent years for their potential in supramolecular chirality manipulation. By applying Harata Kodaka's rule to natural cyclodextrins, chirality inversion materials can be easily created through crystalline self-assembly in an environmentally friendly manner. The future outlook on the rapid development of theory and application in this area is promising.

Summary: Controlling friction by the electric field is a promising approach to improve the tribological performance. This study demonstrates the effective control of assembly structure and microscale superlubricity of a host-guest assembly using the electric field. The assembly behaviors of fullerene derivatives at different probe biases are characterized using STM and DFT techniques, and the controllability of the friction coefficient is confirmed by AFM. The insights gained from this research not only contribute to the understanding of the host-guest assembly mechanism controlled by the electric field, but also promote the application of fullerene in MEMS.

Summary: Through self-assembly experiments, it was found that only ortho-xylene can form hydrogels with cyclodextrin due to its unique molecular conformation, which leads to a stable orientation in the cyclodextrin complex and ultimately gel formation.

Summary: In this study, we achieved symmetry-breaking self-assembly of a defined C-1-symmetric supramolecular structure by the synergistic effects of weak binding forces. The flexible capsule framework undergoes a large structural change upon guest binding, forming a distorted resorcin[4]arene hexameric capsule with an asymmetric cavity. The location of the chiral guest in the anisotropic environment leads to modulation of its Electric Dipole (ED) and Magnetic Dipole (MD) transition moments, resulting in increased emission quantum yield and circularly polarized luminescence.

Summary: This paper fabricates anion exchange membranes (AEM) with a macrocyclic host-guest structure and dynamic self-protection, which exhibit high ionic conductivity and alkali stability. The membranes achieve a hydroxide conductivity of 114 mS cm-1 at 80 degrees C and maintain 93% of their pre-test performance even after immersion in 5 M KOH at 80 degrees C for 1000 h. The highest peak power density of 406 mW cm-2 at 60 degrees C is achieved after the assembly of a single cell. Therefore, the new design using a long chain structure containing both host-guest as side chains is a promising direction for improving AEM performance.

Summary: In this study, artificial light-harvesting systems with a fluorescence resonance energy transfer (FRET) process were successfully obtained in an aqueous solution. An amphiphilic pyrene derivative with two 4-vinylpyridium arms (Pmvb) was designed and synthesized, which could interact with cucurbit[8]uril (CB[8]) to form supramolecular polymers in the solution. The supramolecular polymers showed a significant enhancement of fluorescence, making Pmvb-CB[8] an ideal energy donor for constructing artificial light-harvesting systems. Two different fluorescence dyes, Rhodamine B (RhB) and Sulforhodamine 101 (SR101), were introduced as energy acceptors to fabricate two different artificial light-harvesting systems. The obtained systems demonstrated efficient energy transfer from Pmvb-CB[8] to RhB or SR101 with high energy transfer efficiency.

Summary: This study investigates the complex conversion of the cisplatin-1-methyluracil complex to aqua species under various conditions. The composition of the products depends on the sample history, showing a diverse range of compounds with different condensation patterns and NH3 ligand losses. Analysis using H-1 NMR and ESI-MS spectroscopy reveals the presence of various species with different metal nuclearity, stoichiometry, and Pt oxidation state, suggesting a heterogeneous mixture rather than a mixture of oligomers of different sizes.
