AI Article Synopsis
- A new type of molecular cage, combining oxa- and aza-calix[4]arene, was created with a stable cavity surrounded by aromatic rings through efficient chemical reactions.
- X-ray analysis showed the cage can trap two THF molecules inside its cavity.
- The cage can selectively sense fluoride ions in a non-polar solvent, resulting in a noticeable color change, while adding alcohol (CHOH) restores its original color.
Article Abstract
An oxa- and aza-calix[4]arene hybrid molecular cage with a large, shape-persistent cavity wrapped by aromatic rings was designed and synthesized via multifold efficient SAr reactions. X-ray single-crystal analysis revealed that two THF molecules were encapsulated in the central cavity. Selective sensing of F in apolar solvent leads to naked eye discriminable color change. Addition of CHOH would recover the color of the molecular cage.

Endohedral and exohedral fullerenes have both been employed as electron acceptors in polymer solar cells (PSCs). However, their differences in hot-electron relaxation dynamics remain unclear. Previous studies have shown that the location of a single atom, whether inside or outside the fullerene cage, results in significant differences in charge distribution.

Sativene-related sesquiterpenoids including -sativene analogs are a large member of fungal secondary metabolites with phytotoxic and growth-promoting effects on different plants. In this report, a series of sativene-related sesquiterpenoids with diverse carbon skeletons (-, sativene/isosativene/-sativene/cyclosativene/-isosativene ring systems) were isolated from the plant pathogenic fungus based on a molecular networking strategy. The undescribed structures were elucidated based on NMR spectra, X-ray diffraction analysis, chemical derivation, and calculated electronic circular dichroism calculations.

Binge eating (BE) is a highly pervasive maladaptive coping strategy in response to severe early life stress such as emotional and social neglect. BE is described as repeated episodes of uncontrolled eating and is tightly linked with comorbid mental health concerns. Despite social stressors occurring at a young age, the onset of BE typically does not occur until adulthood providing an interval for potential therapeutic intervention.

The recent detection of benzonitrile (CHCN) in the interstellar medium is one of the most fascinating discoveries in astrochemistry and molecular astrophysics. However, the mechanism of its formation in interstellar ices remains unclear. Here, we report the first evidence for the direct synthesis of benzonitrile through the radiation-induced transformations of an isolated CH···HCN complex in inert rigid media at cryogenic temperature (4.
