Stretchable electronics have attracted significant attention from academia and industry due to their potential application in advanced wearable and implantable electronics. Polymer semiconductors are one of the most promising semiconductor materials for constructing stretchable transistors. Several approaches have been reported to improve the stretchability of polymer semiconductors, including physical blending and molecular engineering. Molecular engineering is one of the most effective methods to prepare intrinsic stretchable semiconductor materials. Hybrid siloxane chains can bring polymer semiconductor decreased elastic modulus, glass transition temperature, and crystallinity, which is expected to improve its mechanical properties. In view of this, our group synthesized a series of novel hybrid siloxane-based side chains to replace alkyl side chains to improve the flexibility of polymer chains and reduce the crystallinity of films. The effect of side chain structure on the aggregate-structure and electrical properties of the conjugated polymers was systematically investigated.
