transport property (n‐type). Although ambipolar properties have been demonstrated from specially designed conjugated polymers, only a few examples have exhibited ambipolar transport properties under limited conditions. Furthermore, there is, as yet, no example with ‘equivalent’ hole and electron transport properties. We describe the realization of an equivalent ambipolar organic field‐effect transistor (FET)
作为常规共轭聚合物的特征,人们普遍认为共轭聚合物既具有高空穴传输性能(p型),又具有高电子传输性能(n型)。尽管已经从特别设计的共轭聚合物中证明了双极性性质,但是只有少数例子在有限的条件下表现出双极性传输性质。此外,到目前为止,还没有具有“等效”空穴和电子传输性质的示例。我们通过使用单组分可见光-近红外吸收二酮
