Metallo-Supramolecular Polymerization: A Route to Easy-to-Process Organic/Inorganic Hybrid Materials

摘要

The self-assembly polymerization of ditopic macromolecules via metal-ligand binding is a facile route for the preparation of metallo-supramolecular polymers (MSPs). We herein review our recent work focused on the synthesis and investigation of metallo-supramolecular polymers based on 2,6-bis(l'-methylbenzimidazolyl)pyridine endcapped poly(p-phenylene ethyn-ylene) and poly(p-xylene) macromonomers. These materials are readily solution-processable and display appreciable mechanical properties as well as other attractive properties such as specific opto/electrical functions or high thermal stability. Our work illustrates that metallo-supramolecular polymerization offers an attractive approach to assemble high-molecular-weight macromolecules from well-defined, easy to process precursors. Variation of the ditopic ligands and metal ions allows one to easily tailor the desired properties.
