A one-dimensional (1D) metal-organic caged framework (YMOF-Y) was obtained via self-assembly of yttrium cations with a U-shape imidazoliumbased ligand and the structure was elucidated by single-crystal X-ray diffraction analysis. The YMOF-Y has a unique 1D chain structure composed of octa-imidazolium based cages. Inside the cage, an inner Y4 cluster connected to yttrium cations of the cage through
通过钇阳离子与U形咪唑鎓基配体的自组装获得一维(1D)金属有机笼状骨架(YMOF-Y),并通过单晶X射线衍射分析阐明其结构。所述YMOF-Y具有基于辛咪唑笼构成的独特1D链结构。在笼内,存在通过甲酸阴离子连接到笼的钇阳离子的内部Y 4簇。YMOF-Y的微孔率和柔韧性可以通过用碱金属溶液洗涤从笼子中空前的合成后去除 Y 4簇来提高。去除Y 4 正如二氧化碳吸附测量和变温粉末 X 射线衍射分析所证实的那样,簇反映在金属有机骨架 (MOF) 性质的显着变化中。
