Polymer semiconductors hold tremendous potential for applications in flexible devices, which is however hindered by the fact that they are usually processed by halogenated solvents rather than environmentally more friendly solvents. We herein present an effective strategy to boost the solubility of high-performance polymer semiconductors in non-halogenated solvents such as tetrahydrofuran (THF) by appending hydroxyl groups in the side chains.

1 Introduction The most significant advantage of polymer semiconductors over the inorganic counterparts is their intrinsic flexibility, stemming from the nature of molecular materials.[1-9] Leveraging this unique advantage, polymer semiconductors are considered as ideal candidates for various flexible applications, including electronic paper, electronic skin, wearable electronics, and man–machine interface.[10-17] As the fundamental building blocks of flexible devices, stretchable organic...
