Synthesis and Characterization of Novel Thiophene-Based Electroactive Polymers
MetadataShow full metadata
Electroactive polymers show great promise in a variety of applications, from chemical sensors to energy storage. Their properties such as solubility and band gap can be tailored through the strategic addition of substituents to the monomer. Extended conjugation monomers, which feature a central ring between electroactive moieties, were synthesized via different palladium catalyzed coupling reactions such as Negishi and Stille couplings. These monomers along with thiophene-based non-extended conjugation monomers were then polymerized chemically and electrochemically. Due to the color change these polymers exhibit during different redox states, spectroelectrochemistry was conducted to determine their band gap. Analysis of these compounds elucidated the impact different substituents had on the resulting polymers.
