주제: A Molecular Design Strategy for Green Solvent-Processable and Stable Polymer Semiconductors toward Applications

Abstract: Polymer semiconductors hold promise for high-performance organic electronics, yet their reliance on harmful solvents and vulnerability under extreme conditions limit their practical use. Addressing these challenges, we developed a molecular design strategy incorporating asymmetric substitution and ionic pendant groups into conjugated polymers. This approach enables green solvent processability and enhances stability against humidity, heat, and mechanical stress. Additionally, a size-selective ionic crosslinking method using oligo(ethylene glycol) pendant groups and metal ions improves mechanical softness and toughness without sacrificing conductivity. This innovation supports robust stretchable electronics with enhanced humidity resistance and temperature-driven charge accumulation. Our integrated strategy advances environmentally friendly and mechanically compliant polymer semiconductors, offering new opportunities for applications in sustainable sensors and energy devices.
