The concept of dendritic networks via four bis(2,2‘:6‘,2‘ ‘-terpyridine)ruthenium(II) connectivities was utilized to create “dendritic methane”-type metallomacromolecules. In addition, two structurally isomeric metallodendrimers (16 and 17) were designed, synthesized, and characterized. These two isomers were spectrally alike and displayed very similar physical and chemical properties; however, the
通过四个双(2,2':6',2''-三联吡啶)钌(II)连接的树枝状网络的概念被用来创建“树枝状甲烷”型金属大分子。此外,设计、合成和表征了两种结构异构的金属树枝状聚合物(16 和 17)。这两种异构体在光谱上相似,并显示出非常相似的物理和化学性质;然而,这些分子的内部密度和空隙区域是通过循环伏安法来区分的。描述了内部和外部树枝状分支的体积对三联吡啶-钌配合物的影响。类似的合成策略允许制备两代不具有外部抗衡离子的中性金属大分子(33 和 36)。描述了这些内部电荷平衡的中性物种的好处,
