Multiple Anion-Coordinated Assemblies Based on a C₂-Symmetric Stilbene-Hydrazone- Urea Ligand: Structural Transformations, Guest Encapsulation, and Photo-Responsive Behavior
This study reports a C₂-symmetric stilbene-hydrazone-urea ligand that forms anion-directed supramolecular assemblies with distinct geometries, enabling phosphate-triggered guest release and photo-induced disassembly via concurrent E/Z isomerization of both C=C and C=N bonds.
