Summary: Although weak intermolecular interactions play a crucial role in key processes, their characterization is still lacking. Environmental and structural variations have been shown to influence chlorine isotope effects, which may obscure mechanistic interpretations and analytical protocols in dehalogenation processes.

Summary: Enhanced guest-pair interactions in the CB[8] cavity were quantitatively determined using SMFS, showing how dynamic conformational changes can affect the rupture force of CB[8]-mediated heteroternary complexation. SMFS was also utilized for detecting methyl viologen based on competitive host-guest interactions in CB[8] or CB[7.

Summary: The study focuses on the kinetics of a water-soluble host-guest system based on cucurbit[8]uril and two DTE photoswitches, demonstrating a method to control the binding kinetics in supramolecular systems using external stimuli. By modifying the structure of the DTE guest molecule, it is possible to significantly slow down the formation/dissociation rates of pseudorotaxane structures, leading to the emergence of a competitive metastable product with important impact on the overall binding kinetics. Additionally, the dissociation kinetics of the host-guest system can be controlled by approximately 100-fold by switching between closed and open DTE isomers.

Summary: The study successfully fabricated a supramolecular luminescence system with tunable fluorescence emissions ranging from yellow to green by assembling a simple fluorescent molecule, 4-(pyren-1-yl)-1-(4-vinylbenzyl)pyridin-1-ium chloride (PPD), and cucurbit[n]uril (CB[n], n = 7, 8) via host-guest interactions. This system exhibited enhanced emission efficiency and longer fluorescence lifetime, making it suitable for applications in fluorescent ink and potential for information encryption materials.

Summary: Over 6.2 million people worldwide suffer from moderate to severe vision loss due to corneal disease. While transplantation with allogenic donor tissue is sight-restoring for many patients with corneal blindness, this treatment modality is limited by long waiting lists and high rejection rates. Host-guest interactions have emerged as an important crosslinking strategy for cytocompatible, minimally invasive, injectable tissue substitutes.

Summary: Pillar[n]arenes, a new type of pillar-shaped host molecule, exhibit versatile and unique host-guest behaviors in host-guest chemistry. Solid-state host-guest complexation offers advantages such as cavity-size dependency, efficient complexation, and easy isolation and reuse. This review discusses recent developments in solid-state host-guest complexation using crystalline pillar[n]arenes, networks containing pillar[n]arenes, pillar[n]arene-assembled surfaces, and solid-state organic polymers.

Summary: We propose a novel method to examine host-guest-solvent interactions in solution from their gas phase structures. By conducting experiments and quantum chemical calculations, we establish the corresponding relationship between the structure of the complex in the gas phase and the stable conformer in solution.

Summary: Researchers have discovered and characterized a family of all-hydrocarbon, all-p-conjugated [n]cycloparaphenylene-PAH host-guest complexes. They have built a theoretical framework to select these complexes and predict their stabilities. This research offers new opportunities for bespoke PAH separation or remediation materials.

Summary: The design of high-affinity synthetic host-guest complexes is crucial for constructing novel supramolecular assemblies, functional materials, molecular probes, artificial signal transduction events, and interfaces with the biological world. This review discusses recent achievements in designing 1:1 host-guest complexes with exceptional stabilities exceeding 10(6) M-1. The relationships between thermodynamic constants and structural parameters are analyzed, and the design features of high-affinity hosts are discussed, considering different solvents and noncovalent interactions for complex stabilization. Hints for future design of synthetic receptors with high affinity and selectivity are provided.

Summary: We developed a new synthetic method to construct supramolecular A(8)B(n) (n=1, 2, 4) miktoarm star copolymers through host-guest complexation. The formation of these copolymers was confirmed by various analytical techniques. The miktoarm copolymers exhibited phase separation in bulk, and the micro-Brownian motion of the A(8)B(4) structure was enhanced due to weak segregation interaction between immiscible arms.
