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