A route was explored to synthesize a new iodine-functionalized spiropyran to later incorporate into poly-(3-hexylthiophene) (P3HT) polymers via a Stille cross-coupling reaction. P3HT oligomers of approximately 9 monomers were synthesized using GRIM polymerization and procedures known in literature, as it is a popular polymer used for studying conjugated polymeric systems and developing organic semiconductors. By synthesizing and functionalizing spiropyrans with P3HT polymers of varying lengths, we hope to analyze the effects spiropyran switching may have on the semiconductive properties of P3HT polymer systems of different lengths.
