报道了一种多组分配位驱动的自组装方法，首次合成了基于三联吡啶的形状保持的二维D-6 h超大分子轮辐轮。以化学计量比（1：6：12）混合核心T6、边缘T3和Zn-II或Cd-II离子允许通过几何和热力学控制以94%的分离产率选择性地产生高度对称的辐条轮。产物的特征在于结合行波离子迁移质谱和NMR技术连同TEM成像，这与计算机模拟一致。
An approach to multicomponent coordination-driven self-assembly of the first terpyridine-based, shape-persistent, giant two-dimensional D-6h supramacromolecular spoked wheel is reported. Mixing core T6, rim T3, and Zn-II or Cd-II ions in a stoichiometric ratio (1:6:12) permitted the selective generation of a highly symmetric spoked wheel in 94% isolated yield via geometric and thermodynamic control. The products were characterized by a combination of traveling-wave ion mobility mass spectrometry and NMR techniques together with TEM imaging, which agreed with computational simulations.
