A few high performance semiconducting polymers with mobility higher than 10 cm2V−1s−1 has been reported in recent years.&lt;span style="font-size:10.8333px"&gt; &lt;/span&gt;As compared with p-type polymer semiconductors, the development of n-type polymers is obviously lagged. Although a few of n-type polymer field-effect transistors (FETs) also have been demonstrated impressive electron mobilities above 5.0 cm2 V–1s–1, their electron mobility and air-stability are still pale. Moreover, comprehensively excellent copolymers with easy synthetic method, high molecular weight, good solubility, good solution-processability together with excellent charge-carrier transporting characteristics and good device stability are still a big challenge in the development of polymeric electronics. In this presentation, I will introduce our exploration in this regard, including design concept, synthesis of both p- & n-type copolymers, fabrication of OFET devices, and investigation of their electronic properties.
