以半撓性配體5,5'-聯嘧啶做為輔助配體製備含疊氮磁性配位聚合物

Azide-based Magnetic Coordination Polymers with a Simi-flexible Auxiliary Ligand of 5,5'-bipyriminde

摘要


半撓性配體5,5'-聯嘧啶不只具連接多個金屬離子形成多維聚合物的能力,還能透過橋接嘧啶環有效傳遞金屬離子間磁作用,除此之外,配體能依需求旋轉兩個嘧啶環靈活調控不同配位構型,令聚合物具有豐富多樣的結構與磁性,相當適合作為輔助配體製備磁性配位聚合物。本文簡單描述利用5,5'-聯嘧啶作為輔助配體,製備含疊氮磁性配位聚合物的自組裝合成、結構與磁性。

並列摘要


The semi-flexible ligand, 5,5'-bipyridine, would not only function as a potential bridging linker to connect the metal ions into a multidimensional structure but would also mediates magnetic interactions effectively between metal ions through the bridging pyrimidyl group. In addition, the sufficient flexibility and adaptability of the ligand can be achieved by twisting its two pyrimidyl rings into various coordination geometries needed and resulting diverse frameworks. In this report, we describe the self-assemblies, crystal structures and magnetic properties of azide-based magnetic coordination polymers with 5,5'-bipyridine.
