Summary: The research describes a new type of inorganic host material, titanium-oxide or polyoxotitanate clusters, which can encapsulate inorganic molecules or ions. A specific molecular cage, Ti-18, was found to encapsulate an entire organic ethylenediamine ion and demonstrate exceptional versatility in balancing charges and facilitating reactions. Ti-18 exhibits strong light absorption due to ethylenediamine coordination and shows superior photocatalytic activity compared to anatase TiO2.

Summary: Cycloparaphenylene nanocarbons (CPPs) are organic semiconductors with controllable structures and unique optoelectronic properties. In this study, CH-pi interactions were found to enable the inclusion of redox-active metallocene guests in CPPs, enhancing stability through additional supramolecular forces. This finding is significant for the design of bespoke nanoelectronics and artificial molecular machines.

Summary: This study successfully fabricated an ultrastretchable TENG that can simultaneously heal fractures and abrasions at room temperature, demonstrating impressive stretchability and self-healing properties. The TENG showed excellent electrical outputs in contact-separation mode and could quickly recover electrical performance if stretched to break or scratched to wear out, indicating great potential for flexible and wearable electronics applications.

Summary: In this study, the aryl-group achiral molecular tweezers were found to effectively include chiral guest molecules via halogen bonding and other noncovalent interactions. Experimental and computational calculations revealed the formation of stable 1:1 host-guest complexes, demonstrating the transfer of chirality to achiral host molecules at the supramolecular level.

Summary: Three novel iron(II) coordination polymers were synthesized using the linker 1,3,5-tris((1H-1,2,4-triazol-1-yl)methyl)benzene (ttmb). The single-crystal structures revealed that all three compounds form a double-chain structure with the iron atoms being bridged by two ttmb linkers. The iron(II) ions are surrounded by N4 donor atoms from the triazole groups of ttmb, along with coordinating water or isothiocyanato ligands.

Summary: By synthesizing thermoplastic polyurethanes with multiple dynamic bonds, self-healing elastomers with high strength and efficiency were successfully prepared. The self-healing mechanism can be explained from the perspective of aggregate structure, degree of microphase separation, and molecular dynamics.

Summary: In this study, a series of updated supramolecular polyurethanes were successfully synthesized by incorporating hierarchical hydrogen-bonding motifs into the polymer matrix and subsequently coordinated with Zn(2+) ions. The resulting supramolecular elastomers exhibited superior mechanical properties compared to previously reported room-temperature self-healing materials. Additionally, a bilayer polymer film with a gradient distribution was fabricated, which achieved rapid self-healing at ambient temperature.

Summary: This study reports a cascaded guest delivery between two anionocages, where binding of K+ ions triggers the release and delivery of another guest, and elimination of K+ enables reversed guest delivery. Integrative self-sorting of anionocages is achieved for the first time, leading to enhanced guest binding affinities in heteroleptic cages.

Summary: The kinetics of ligand exchange at a ZnII center confined in a biomimetic environment were studied by 1H NMR spectroscopy. It was found that the exchange was slow under dry conditions but much faster in the presence of water. The study also showed that water molecules played a catalytic role in the exchange process, highlighting the importance of water and micro-environment in metal ion lability.

Summary: Ligands derived from cis,cis-1,3,5-triaminocyclohexane (TACH) with pendant heterocycles as outer-sphere H-bond donors were prepared. Coordination to Cu(I) created a hydrogen-bonding cavity that stabilized (pseudo)halide anions. Reaction with divalent cations showed a range of protonation states, coordination geometries, and H-bonding interactions.

Summary: Preorganization is a crucial concept in supramolecular chemistry, where preorganized receptors enhance binding by minimizing the organization costs. This study presents a method to quantify the hidden costs of receptor organization and confirms the impact of solvent polarity on complex stability and conformational organization.
