Supramolecular Eu(III)₄L₄ Tetrahedra-Based Films for Luminescence Sensing of Volatile Amines with Sub-ppt-Level Detection Limit

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Metal–organic cages are a class of discrete supramolecular architectures endowed with well-defined cavity and diverse functionalities, offering broad range applications that, however, predominantly confined to liquid phases. In this study, we present the self-assembly Eu(III)4L4 tetrahedra, constructed from triarylborane-cored tritopic tridentate ligands, which were fabricated into spin-coated films bright emission, smooth surfaces, uniform thickness. These demonstrated ultralow detection limits for series volatile amines, reaching sub-ppt level. This work serves as compelling example preparation application metal–organic-cage-based films, paving way broader scenarios.

Efficient Synthesis of Arylhydrazone Capsule with Single Precursor for Encapsulation of C₆₀ and C₇₀

Chemistry - An Asian Journal, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

Abstract Molecular cages are distinguished supramolecular structures with stable cavities, enabling applications in molecular recognition, catalysis, and drug delivery. While the synthesis of purely organic is less common often hindered by entropy‐related challenges irreversible reactions. In this study, we present a novel single‐precursor strategy featuring dual aldehyde hydrazine units to facilitate ring closure via hydrazone chemistry. This approach yielded double‐layered aromatic arylhydrazone macrocycle 88% yield. Furthermore, electron‐rich properties showed strong binding electron‐donor fullerene guest C 60 70 .
