Assembly Modulation by Adjusting Countercharges of Heterobimetallic Supramolecular Polymers Composed of Tris(spiroborate) Twin Bowls

Heterobimetallic supramolecular polymers were prepared by treatment of the supramolecular polymers composed of tris(spiroborate) type molecular connecting modules with a potassium cation. On the other hand, the addition of a barium cation led to dissociation of the supramolecular polymer chain. Modulation of polymer formation was realized by the use of small metal cations as a control factor.

异双金属超分子聚合物可通过将由三(螺硼酸酯)(tris(spiroborate))型分子连接模块构成的超分子聚合物与钾阳离子进行配位处理制得。另一方面，加入钡阳离子会导致超分子聚合物链发生解离。通过以小型金属阳离子作为调控因子，实现了对聚合物形成的调控。
