Recent achievements in conjugated polymer-based gas sensors by side-chain engineering
Recent advancements in conjugated polymer-based gas sensors have highlighted the critical role of side-chain engineering in optimizing organic field-effect transistor (OFET) performance for gas detection. This review provides a comprehensive analysis of how structural modifications of side chains in conjugated polymers affect the electrical properties of OFETs, as well as the sensitivity and selectivity of OFET-based gas sensors. We first explore modifications of alkyl side chains and their impact on the electrical characteristics of conjugated polymers. Then, we discuss how functionalized side chains and additives can significantly enhance sensor performance by improving detection limits and selectivity. Special attention is given to glycol-based side chains, particularly in enhancing NO2 sensitivity, and the role of alkyl side chain length in tuning gas sensing capabilities. This review aims to elucidate the intricate relationships between side chain modifications and sensor performance, offering insights for the development of advanced OFET-based gas sensors with improved sensitivity and selectivity.
