报告摘要：
The self-assembly processes through coordination chemistry for bottom-up construction of nanoscale organic-inorganic objects and patterns have received tremendous attention not only owing to their aesthetic architectures but also to their potential applications in drug delivery, optoelectronics, sensors, magnetic materials, catalysis, etc. To achieve precise assembly of predesigned building units into the predictable and desired structures still remains a great challenge because numerous physical and chemical factors may have a significant influence on the assembling behavior. To overcome the obstacles, our research team devoted our efforts to developing new methodology for coordination-driven self-assembly. Recently, we achieved a complementary complexation pair of terpyridine-based ligands with Cd11 ions.'1 The selective coordination mechanism was elucidated by tandem mass spectrometry and 1H NMR titration experiments, indicating that the auxiliary ion-dipole interactions derived from the dimethoxyphenyl substituents facilitate the spontaneous heteroleptic complex formation under ambient conditions. In order to reduce kinetic errors in a multicomponent self-assembly process, this high-fidelity self-recognition pair was further applied to construction of two multicomponent metallo-supramolecular structures, i.e., an enlarged triangle and a bilayered isogonal hexagon.'12 Their structural characterization was carefully done by NMR spectroscopy, traveling wave ion-mobility mass spectrometry (TWIM-MS), single-crystal X-ray analysis (for the enlarged triangle only), AFM, and TEM. On the other hand, another complementary ligand pair with Zn11 ions was designed and synthesized.M This ligand pair was utilized in preparation of metallo-supramolecular rod-coil P3HT-/j-PEO diblock copolymers. The self-assembled nanostructures of the resultant amphiphilic copolymers in solution were investigated and their dynamic features were demonstrated by reversible complexation-decomplexation reactions. The presented supramolecular methodology highlights the merits of complementary metal-ligand coordination, and offers a new approach to precisely engineering assembled nanostructures. These and other aspects of metallo-supramolecular assemblies will be discussed.
