Beschreibungen/Notizen

• By using a flexible cyclotriphosphazene-functionalized hexacarboxylate, a novel metal-organic framework (ZJNU-60) has been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction. ZJNU-60 consists of dicopper paddlewheel secondary building units interconnected by organic linkers to form a bilayer with a rectangular channel running along the baxis. Upon desolvation, the framework underwent severe distortion and pore contraction, but the permanent porosity has been established as shown in C sub(2)H sub(6), CO sub(2) and CH sub(4) gas isotherms. Furthermore, the activated ZJNU-60a displayed impressive adsorption selectivities toward C sub(2)H sub(6) and CO sub(2) over CH sub(4), indicating the potential for the separation of CO sub(2) and C sub(2)H sub(6) from CH sub(4). This is the first example of a MOF constructed from a flexible cyclotriphosphazene-functionalized hexacarboxylate for selective gas separation.
