Polypyrrole is one example of a conjugated polymer that has many potential applications in this field, including use in batteries, organic solar cells, and chemical sensors. These polymers are very versatile; many different routes for the synthesis of polypyrroles have already been explored, and new ways to synthesize polypyrroles are constantly being developed. This work aims to synthesize poly(2,4-pyrrole-alt-p-phenylene) (Figure 1) using a previously unexplored method. Traditionally, polypyrroles are substituted in the 2,5 position, however this polypyrrole is substituted in the 2,4 position. This bent conformer could afford polypyrroles with unique properties. The experiment has shown successful synthesis of the diisocyanide monomer that is needed to make the target 2,4 polypyrrole. Polymerization studies are ongoing, as the right combination of ligand and copper (1) source is continuing to be tested. However, preliminary results show promise.
