chelating properties of these ligands are compared to those of the bis(8-aminoquinoline) ligands with different linkers between their N8 nitrogen atoms. The N8-linked bis(8-aminoquinoline) ligands have a higher affinity for CuII when the linker includes a three-atom unit or when the linker is linked directly through the N8 atom. Other ligands, including that with a dimethylamino linker on C2, are less
已经制备了连接在两种喹啉的 C2 碳原子上的新双(8-氨基喹啉)配体。当接头包含单原子氨基时,相应的化合物是 CuII 离子的优良螯合剂,并形成相对于 ZnII 螯合具有高金属离子选择性的单核物质。对于双(8-羟基喹啉)类似物,未观察到这种对 CuII 离子的选择性。将这些配体的螯合特性与在其 N8 氮原子之间具有不同接头的双(8-氨基喹啉)配体的螯合特性进行比较。当接头包含三原子单元或当接头直接通过 N8 原子连接时,N8 连接的双(8-氨基喹啉)配体对 CuII 具有更高的亲和力。其他配体,包括在 C2 上具有二甲氨基接头的配体,效率较低,似乎以与二吡啶甲胺相似的亲和力螯合 CuII 和 ZnII。(© Wiley-VCH Verlag GmbH & Co.
