Structural chemistry has been used to guide the rational synthesis and physical properties of novel metal-organic nanodevices. Their self-assembly rules have been explored. A total of 12 different N, S and COO- containing groups have been designed and synthesized with different symmetry and stereoselectivity The novel large-scaffold multifunctional flexible ligands, as well as the synthesis of 18 novel metal organic nanocages, nanotubes and coordination polymers by their self-assembly with metal ions, opened up a new way for the synthesis of metalorganic nanodevices. Among them, a metal nanocage with Oh symmetry, cage volume of more than 1 0 0 0 A3, can accommodate a variety of ions and small molecules, is currently the single crystal structure of the metal nanocage the largest capacity. However, the metal-organic nanotubes (CNTs) with nanotubes connected in series by metal ions are the first reported structure-ordered inorganic nanotube arrays in the world. In addition, a novel semiconductor with paramagnetic properties Ni dimephed Ni layer and two two-dimensional folded lattice compounds. In addition, the first hexagonal CuCN macrocyclic compound in the world and the other novel Of graphite-like CuCN compounds.Metalline and multi-functional ligands are driven by the coordination bond and lead to self-assembly to form metal organic nano-devices with uniform size and specific shape, which is one of the frontiers in the field of chemistry and materials today . However, by designing and synthesizing organic ligands with specific symmetry and stereoselectivity and self-assembly with metal ions to form nanospheres and nanotubes with nanometer size and special functions, they are also in nanotechnology.
