Dendrimeric metallacrowns may include a monomeric metallacrown complex or a dimeric metallacrown complex. In an example, the dendrimeric metallacrown includes the monomeric metallacrown complex and a dendron. In this example, the monomeric metallacrown complex includes a central ion, and a metallomacrocycle attached to the central ion. The central ion is selected from the group consisting of a lanthanide ion, a d-block transition metal ion or rare earth metal ion, and an s-block alkali or alkaline earth metal. The metallomacrocycle includes a repeating sub-unit consisting of a metal ion and a ring ligand selected from the group consisting of a hydroxamic acid derivative and an oxime derivative. The dendron is respectively attached to each of the ring ligands of the metallomacrocycle.
树枝状金属冠可以包括单体金属冠复合物或二聚体金属冠复合物。在一个例子中,树枝状金属冠包括单体金属冠复合物和树枝状化合物。在此示例中,单体金属冠复合物包括一个中心离子和一个连接到中心离子的金属环。中心离子选自镧系离子、d-块过渡金属离子或稀土金属离子、s-块碱金属或碱土金属组成的组。金属大环包括由金属离子和环状配体组成的重复子单元,环状配体选自由羟肟酸衍生物和肟衍生物组成的组。树枝状突起分别连接到金属大环的每个环配体上。
