Various sustainable energy conversion techniques like water electrolyzers, fuel cells, and metal-air battery devices are promising to alleviate the issues in fossil consumption. However, their broad employment has been mainly inhibited by lack of advanced electrocatalysts accelerate sluggish kinetics three involved half-reactions including oxygen evolution reaction (OER), reduction (ORR), hydrogen (HER). Recent advances have witnessed cucurbit[n]uril (CB[n])-directed strategy as a prominent tool develop high performance with either OER, ORR, or HER activities. In this review, recent progress on CB[n]-derived ranging from molecular complexes heterogeneous nanostructures single-atoms for reviewed, future opportunities discussed.

Abstract Lithium‐sulfur (Li‐S) batteries are considered promising candidates for next‐generation high‐energy‐density storage devices; however, their commercialization remains hindered by several challenges. Supramolecular macrocyclic compounds, owing to unique structures and properties, hold significant potential improving Li‐S battery performance. In this study, the inclusion mechanism of lithium polysulfides (LiPSs) cucurbiturils (CB[n], n = 6,7) was systematically investigated. Density functional theory (DFT) calculations were employed analyze recognition capabilities CB[6] CB[7] polysulfides. The results indicate that both effectively encapsulate through non‐covalent interactions. Specifically, exhibits a stronger affinity medium‐chain sulfur species, with most pronounced encapsulation observed Li 2 S 4 . contrast, demonstrates superior efficiency longer‐chain stable occurring 6 Furthermore, molecular dynamics (MD) simulations based on DFT revealed @CB[6] @CB[7] exhibit high stability in electrolytes. These findings suggest CB[7], as supramolecular materials, can inhibit dissolution migration batteries, mitigating “shuttle effect” significantly enhancing cycle life charge‐discharge efficiency. This research provides valuable insights into optimization materials applications.

The development of water-soluble multicharged macrocycles has opened promising pathways in biomedical applications, enabling selective molecular recognition for therapeutic and diagnostic uses. Yet, traditional polyanionic polycationic receptors often face performance limitations under realistic operating conditions. A major drawback is the natural tendency these polycharged hosts to experience increasing screening effects as concentration rises due self-ion pairing phenomena, which can reduce binding efficiency by several orders magnitude. These issues are further intensified when polyionic used high-salinity environments, typically replicate physiological settings, where abundance ions introduces additional that diminish supramolecular affinity a wide range guests. This study presents new approach leverages zwitterionic synthetic with rationally engineered architectures overcome challenges. By incorporation specific structural features, eliminated, effectively making host no longer controlling factor thermodynamics complexation process. Additionally, dual-charged achieve self-contained stabilization, naturally shielding sites from external ion interference Furthermore, ability encapsulate guests, challenging task strong solvation molecules aqueous solution, adds significant value functional versatility macrocycles. Altogether, findings represent advancement design stable adaptable receptor systems complex environments.
