Hierarchical construction of a highly ordered supramolecular array has been, in general, a challenge due to the complexation of building blocks and the hard-to-control weak interactions. Herein, we present a type of well-ordered nanoribbon, which was self-assembled via shape complimentary and hydrophobic effects from the bowl-shaped supramolecular components, which were synthesized by combining designer terpyridine-based monomers and two different metal ions (Ru2+, Zn2+). Interestingly, switching counter ions or changing monomer concentrations, a transformation between a uniform nanosphere and nanoribbon occurred. This opens a door to fabricate readily tailorable, large-scale, supramacromolecular materials.
由于构建块的复杂配位和难以控制的弱相互作用，高度有序的超分子阵列的分级构建通常是一个挑战。在此，我们展示了一种有序纳米带，它是通过碗状超分子组件的形状互补和疏水作用自组装而成的，这些组件是通过结合设计的卟啉基单体和两种不同的金属离子（Ru2+，Zn2+）合成的。有趣的是，通过切换抗衡离子或改变单体浓度，可以在均匀纳米球和纳米带之间发生转变。这为制备可定制、大规模的超分子材料开辟了道路。
