Summary: Para-sulfonato-calix[4]arene has been proven to be a great receptor for biomolecules. In this study, four complexes of para-sulfonato-calix[4]arene with bioactive molecules were presented and their structures were determined by X-ray diffraction. The complexes accommodate biomolecules within the hydrophobic cavity and are stabilized by noncovalent interactions.

Summary: A fluorescence sensing method based on host-guest molecular recognition is proposed for the detection of widely used herbicides paraquat and diquat. The method utilizes calix[6]arene derivatives containing anthracene or naphthalene as pendant fluorophore to recognize paraquat and diquat in hydroalcoholic solution and shows a broad linear response range. The method has been successfully applied to the determination of paraquat in drinking water samples.

Summary: Self-sorting supramolecular polymerization was achieved using chiral calix[5]arene hosts and a dumbbell-shaped fullerene guest, leading to the formation of helical supramolecular fullerene polymers. The controlled supramolecular polymerization was confirmed through diffusion-ordered H-1 NMR (DOSY) and circular dichroism (CD) studies.

Summary: Fluorescent calix[4]arene scaffolds with electron-rich carbazole moiety conjugated at the lower rim have been prepared. The electronic properties of the distal phenolic ring play a major role in the fluorescence quenching in the presence of the N-methyl pyridinium guest. Introducing an electron-donating piperidine fragment into that ring significantly increases the host-guest interactions, while introducing the same fragment into the proximal phenolic ring weakens the fluorescence response.

Summary: The study on a molecular capsule based on a calix[6]arene core reveals unique coordination modes to prevent guest molecule exchange and evaluates the impact of different closing mechanisms on binding ability. The selective binding of different ligands through metal ion coordination highlights the importance of rigidification of receptor conformation. However, increased rigidity may weaken host-guest interactions, affecting the induced-fit behaviors observed in the parent compound.

Summary: Novel integrated photosensitizer-catalyst dyads based on robust host-guest interactions have been developed, showing twice greater efficiency in current photogeneration compared to traditional architecture. The enhanced performance is attributed to optimization of distances between the centers of photosensitizer, catalyst, and semiconductor.

Summary: A new type of macrocyclic arene, calix[n]phenoxazines, based on phenoxazine compounds, has been developed. Calix[3]phenoxazines with different substitutes on nitrogen atoms and methylene bridges have been synthesized with a yield of 30%-70%. The study reveals that calix[3]phenoxazines possess electron-rich cavities, allowing them to selectively encapsulate suitable electron-deficient guests through multiple noncovalent interactions.

Summary: Host-guest drug delivery systems (HGDDSs) have been studied to modify therapeutic agents and improve treatment effects. The targeting ability of HGDDSs needs continuous improvement for the development of precision medicine. In this study, a lactose-modified azocalix[4]arene (LacAC4A) was used as a triple targeting drug carrier for antitumor purposes. LacAC4A showed effective tumor growth suppression through passive targeting, active targeting, and stimuli-responsive targeting. This design principle provides a new material for drug delivery systems.
