The quantitative, single step, self-assembly of a shape-persistent, three-dimensional C3v-symmetric, triptycene-based tris-terpyridinyl ligand initially gives a platonic-based cubic architecture, which was unequivocally characterized by 1D and 2D NMR spectroscopy, mass spectrometry, and single crystal X-ray structural analysis. The unique metal–ligand binding properties of the Cd2+ analogue of this

配体结合特性在立方体,棱柱形和四面体形结构之间产生了浓度依赖性的动态平衡。稀释通过稳定的棱柱状中间体将这个立方转化为两个相同的四面体。增加浓度会逆转这一过程。
