A rigid phenyl-based covalently interlocked macrocycle with inherent porosity
The precise construction of three-dimensional (3D) carbon networks consisting solely of sp2 hybridized atoms has long been pursued in carbon nanoscience. Herein, we report the bottom-up synthesis of a covalently interlocked macrocycle ([2]CIM) featuring a molecular core of 31 benzene units. X-ray cr...

| Résumé: | The precise construction of three-dimensional (3D) carbon networks consisting solely of sp2 hybridized atoms has long been pursued in carbon nanoscience. Herein, we report the bottom-up synthesis of a covalently interlocked macrocycle ([2]CIM) featuring a molecular core of 31 benzene units. X-ray crystallography unambiguously confirmed the covalently interlocked structure of [2]CIM, revealing a rigid 3D architecture with inherent porosity. Its conformational rigidity and solid-state packing enable it to be a promising molecular porous material, exhibiting a specific surface area (SABET) of 507 m2 g−1. Gas absorption studies demonstrated the preferential adsorption of ethane (C2H6) over ethene (C2H4) by the phenyl-based covalently interlocked macrocycle. [2]CIM exhibits a unique gas separation performance among discrete phenyl-based porous macrocycles. |
