Abstract:
The construction of complex artificial supramolecules with specific functions remains a significant challenge in the field of supramolecular chemistry, largely due to the lack of efficient and reliable self-assembly strategies. In response to this challenge, our research group has systematically investigated the influence of ligand geometry on coordination-driven self-assembled structures. Through this work, we have developed a range of innovative self-assembly strategies that enable the construction of metallo-supramolecular architectures with remarkable structural diversity and complexity. Our strategies include multivalency-induced cooperative coordination, dynamic heteroleptic complexation, the design of metalloligand building blocks, and the integration of orthogonal and selective noncovalent interactions. These approaches have allowed us to achieve precise control over the formation of intricate metallo-supramolecular structures, paving the way for new functional materials. This seminar will cover the rational construction of well-defined metallo-supramolecular structures, present a general self-assembly methodology, and explore the hierarchical self-assembly of molecular polyhedrons.
