Abstract

In the last decade, polymeric semiconductors have attracted wide attentions owing to their potential application in organic light-emitting diodes, organic solar cell and organic field-effect transistors. Some polymer materials, especially elastomers, have excellent flexibility, such as strechability, bendability, etc., so polymeric semiconductors are considered as the most promising kind of materials in the future research of flexible electronics. The key point for the flexibility evaluation of polymeric semiconductors is intrinsic mechanical properties, for which, according to relevant works, researchers have already developed some effective approaches to determine, including stretching method, sinusoidal buckling technique, nanoindentation method, and AFM nanomechanical mapping. On the other hand, a variety of ideas for designing flexible polymeric semiconductor materials have emerged and can be classified into supramolecular strategy, "chain flexibilization" strategy, and doping/blending strategy. It is noteworthy that the orthogonal dynamic non-covalent interaction is a fundamental molecular mechanism to induce the flexibility of conjugated polymers. And the tactic based on this mechanism provides a universal method to design flexible semiconductor materials and deserves further studies. This review gives a summary on the intrinsic mechanical properties and design strategies of flexible polymeric semiconductor materials based on the state-of-the-art researches.
