New Polymeric Materials Incorporating Heteromatic Phosphabenzene Units
Abstract
The proposed project described the incorporation of aromatic phosphorus heterocycles into polymer main chains and side chains. While pyridine and thiazole have been explored extensively in polymer chemistry, the phosphorus analogs (phosphinine and thiaphosphole) have yet to be incorporated into macromolecular structures. Monomer syntheses were explored for both ring systems and polymerization efforts resulted in some success for phosphinine-containing oligomers. Synthetic method development for both phosphinine and thiaphosphole proved challenging, and a successful efficient route to polymerizable monomers has not yet been established. Further efforts have looked at other phosphorus containing monomers in conjugated structures. This project has also been expanded to controlled polycondensation for semiconducting polymers. Furan, which is a bio renewable monomer, has been explored in controlled polycondensation. High molecular weights could not be achieved due to aggregation but the furan was incorporated into an alternating polymer with thiophene to obtain solution-processable materials.
