Synthesis of Fluoro-Bridged Ho 3+ and Gd 3+ 1,3,5-Tris(4-carboxyphenyl)benzene Metal-Organic Frameworks from Perfluoroalkyl Substances

A new fluoro-bridged rare-earth (RE) metal-organic framework consisting of 15-connected nonanuclear and 9-connected trinuclear clusters {[RE -(μ -F) (H O) ][RE (μ -F)(H O) ](HCO ) -(BTB) }·(solvent)x (RE = Ho and Gd ) was synthesized through the transformation of a dimeric complex formulated as bis(...

Description
Summary:A new fluoro-bridged rare-earth (RE) metal-organic framework consisting of 15-connected nonanuclear and 9-connected trinuclear clusters {[RE -(μ -F) (H O) ][RE (μ -F)(H O) ](HCO ) -(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 (H BTB). 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.
