High Temperature Resistant Organic/Inorganic Hybrid Polymers: An Architectural Study
Abstract
This project addressed the development of a new class of metal/organic supramolecular polymers, which are prepared by the self-assembly of ditopic ligands and appropriate metal ions. The ditopic ligand consists of two 2,6-bis(1'-methyl-benzimidazolyl)pyridine ligands, which are connected to each other by either a conjugated poly(p-phenylene ethynylene) (PPE) core or a poly(p-xylyene) (PPX) core. The metal/organic supramolecular polymers based on ditopic poly(p-xylyene) macromonomers were investigated as easy-to-process high-temperature-resistant materials. We demonstrated that these supramolecular materials are indeed easily processably in common organic solvents and that their thermal stability is very similar to that of common (but intractable) poly(p-xylenes). In addition, investigations of metallo-supramolecular polymers based on the ditopic poly(p-phenylene ethynylene) macromonomers have demonstrated the potential of these systems as sensors for chemical warfare agents. In particular, we have shown that these materials and selected derivatives exhibit significant changes in fluorescence in the presence of organophosphates and that different organophosphates show different responses.
