  Size-Selective Crystallization of Homochiral Camphorate Metal–Organic Frameworks for Lanthanide Separation

  摘要：

  Lanthanides (Ln) are a group of important elements usually found in nature as mixtures. Their separation is essential for technological applications but is made challenging by their subtly different properties. Here we report that crystallization of homochiral camphorate metalorganic frameworks (MOFs) is highly sensitive to ionic radii of lanthanides and can be used to selectively crystallize a lanthanide element into predesigned MOFs. Two series of camphorate MOFs were synthesized with acetate (Type 1 with early lanthanides LaDy) or formate (Type 2 with late lanthanides TbLu and Y) as the auxiliary ligand, respectively. The Ln coordination environment in each type exhibits selectivity for Ln(3+) of different sizes, which could form the basis for a new cost-effective method for Ln separation.

  Three isomorphous homochiral 3D lanthanide coordination polymers ([Ln(HCOO)(D-cam)]n, where Ln = Dy (1), Ho (2), Er (3)), featuring sra topology have been constructed from triple-strand helical Ln–O}n rod SBUs and chiral D-cam spacers. Thermogravimetric analyses show the remarkable thermal stabilities of all three rigid lanthanide camphorate frameworks up to 450 °C.

  由三股螺旋Ln-O}n棒状SBU和手性D-cam间隔物构建了具有sra拓扑结构的三个同构的手性3D镧系元素配位聚合物（[Ln(HCOO)(D-cam)]n，其中Ln = Dy (1)、Ho (2)、Er (3)）。热重分析表明，所有三个刚性镧系樟脑酸盐骨架在450°C以下都具有卓越的热稳定性。
