Light-triggered Supramolecular Isomerism in a Self-catenated Zn(II)-organic Framework: Dynamic Photo-switching CO₂ Uptake and Detection of Nitroaromatics.

ABSTRACT: A self-catenated Zn(II)-organic framework formulated as [Zn₂(3,3'-bpeab)(oba)₂]·DMF (1) exhibiting a six-connected 4⁴·6¹⁰·8 topology has been successfully synthesized through the mixed-ligand of kinked 3,3'-bis[2-(4-pyridyl)ethenyl]azobenzene (3,3'-bpeab) and 4,4'-oxybis-benzoic acid (H₂oba) under solvothermal condition. UV light triggers isomerization of complex 1 in a single-crystal-to-single-crystal (SCSC) manner, giving rise to a conformational supramolecular isomer 1_UV through the pedal motion of photoresponsive double bonds. Dynamic photo-switching in the obtained light-responsive supramolecular isomers leads to instantly reversible CO₂ uptake. Furthermore, the ligand originated fluorescence emission of water-resistan
