Summary: This report investigates the complexation of azobenzenedyes with cucurbit[7]uril (CB7). The results show that CB7 encapsulates the protonated form of the azobenzene and stabilizes the dye conjugate acid, leading to an increase in pK(a). Molecular modeling suggests that this complex formation is stabilized by ion-dipole interactions, inclusion of the azobenzene ring within the CB7 cavity, and a hydrogen bond between the azo nitrogen and CB7 carbonyls. CB7 complexation not only enhances the stability and hydrophilicity of azobenzene but also offers potential applications in pigment and prodrug development, as well as creating dye displacement assays.

Summary: We report complex formation between the chloroacetamide 2,6-diazaadamantane nitroxide radical (ClA-DZD) and cucurbit[7]uril (CB-7), which significantly immobilizes the radical and allows for reliable measurement of interspin distances. These findings have important implications for supramolecular recognition-enabled long-distance DEER measurements at near physiological temperatures.

Summary: Spectroscopic and computational techniques were used to study the complexation of gabapentin and its lactam form with cucurbit[7]uril in aqueous solution. The results showed that cucurbit[7]uril can form 1:1 complexes with both gabapentin and its lactam form, with a higher preference for the lactam form. The encapsulation of gabapentin within the cavity of cucurbit[7]uril also increased the rate of lactamization, as revealed by NMR spectra.

Summary: In this paper, CB[7]-mediated three-dimensional gold nanoassemblies were prepared to enhance the electrochemical detection of amino acids. The size of gold nanoparticles significantly affects the stability and detection sensitivity of the nanoassemblies. The volume of gold nanoassemblies initially increased and then decreased with the increase of CB[7] concentration. The 3D gold nanoassemblies composed of 16 nm AuNPs and 100 mu mol/L CB[7] showed excellent stability and maximum volume, providing more sensitive detection for a variety of amino acids.

Summary: Nanoparticle surfactants (NPSs) are powerful tools for stabilizing oil-water interface and constructing all-liquid devices. However, at molecular-scale size, NPSs exhibit dynamic adsorption and liquid-like state due to reduced binding energy. In this study, a supramolecular NPS model called CB[7] surfactant is described, which can form elastic films with excellent mechanical properties at the oil-water interface. The high binding energy of CB[7] surfactant keeps it in a jammed state, transforming the interfacial assemblies from liquid-like to solid-like state and enabling the structuring of liquids. Using CB[7] surfactants as emulsifiers, various emulsions can be prepared, and the assembly/disassembly and jamming/unjamming processes can be controlled, allowing for the reconfiguration of all-liquid constructs.

Summary: Accurately determining ultra-high binding affinities in supramolecular host-guest chemistry is challenging due to sensitivity constraints of common titration methods. Competitive titrations with well-established reference compounds can provide a reference scale for determining high binding affinities, such as with the host cucurbit[7]uril (CB7) in the range from 10^3 to 10^15 M^-1. These commercially available reference compounds will aid in future research on stimuli-responsive host-guest systems.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
