中南大学王平山团队报道了镶嵌八面体的模块化构造及其分层球面聚集行为。相关研究成果发表在2022年8月5日出版的《德国应用化学》。

协调驱动的自组装导致了各种美学多面体和高级功能的出现。与大量报道的具有复杂和巨大骨架的二维超分子相比，多面体的构造受到基本多边形作为面板的限制。

该文中，研究人员报告了通过模板驱动自组装以金属有机模块为面板的镶嵌三角形和镶嵌八面体的模块化合成。这些结构具有约10.9nm的直径和大于84kDa的分子量。有趣的是，纤维状和球状纳米结构可以通过分层自组装分别由镶嵌三角形和八面体形成。此外，通过碳纳米管的杂化，超分子表现出明显的电化学还原CO₂为CO的活性。

Abstract: Coordination-driven self-assembly has led to the formation of various aesthetical polyhedrons and advanced functions. Compared to plentiful reported two-dimensional supramolecules with complex and giant skeletons, the constructions of polyhedrons are limited by using basic polygons as the panels. Herein, we report the modular synthesis of the tessellated triangle and tessellated octahedron with metal-organic module as the panel via template-driven self-assembly. These architectures possess diameters on the order of 10.9 nm and molecular weights greater than 84 kDa. Interestingly, fiber and spherical-like nanostructures could be formed by tessellated triangles and octahedrons through hierarchical self-assembly, respectively. In addition, the supramolecules exhibit evident electrochemical reduction activity for CO  2  to CO with the hybridization of carbon nanotubes.
