A new fluoro-bridged rare-earth (RE) metal-organic framework consisting of 15-connected nonanuclear and 9-connected trinuclear clusters {[RE-(μ-F)(HO)]RE(μ-F)(HO)-(BTB)}·(solvent)x (RE = Ho and Gd) was synthesized through the transformation of a dimeric complex formulated as bis(2,2'-bipyridine)tetrakis(μ-2-fluorobenzoato-,')-bis(2-fluorobenzoato)diRE(III) with the bridging linker 1,3,5-tris(4-carboxyphenyl)benzene (HBTB). The rare-earth metal ions Ho and Gd were also found to remove fluorine from other organo-fluorine compounds such as perfluorohexanoic acid (PFHxA) and perfluorooctanoic acid (PFOA), resulting in the new fluoro-bridged RE-MOFs.
通过将一种二聚配合物[双(2,2'-联吡啶)四(μ-2-氟苯甲酸根,'-双(2-氟苯甲酸根)二稀土(III)]与桥连配体1,3,5-三(4-羧基苯基)苯(HBTB)进行转化，合成了一种新型氟桥连稀土(RE)金属有机框架{[RE-(μ-F)(HO)]RE(μ-F)(HO)-(BTB)}·(溶剂)x （RE = Ho和Gd），该框架由15连接的九核簇和9连接的三核簇组成。还发现稀土金属离子Ho和Gd能从其他有机氟化合物如全氟己酸(PFHxA)和全氟辛酸(PFOA)中去除氟，从而生成新的氟桥连稀土金属有机框架。
