聚对苯乙撑衍生物(PPVs)是有机电子学中研究最广泛的p型聚合物之一。PPV的电子迁移率一般低于10(-4)cm(2)V-1 S(-1)，因此阻碍了其在高性能高分子场效应晶体管和有机光伏领域的应用。在这里，我们设计并合成了一种新型的缺电子PPV衍生物--苯并二呋喃二酮基PPV(BDPPV)。这种新的PPV衍生物在常温下(比其他PPV高4个数量级)表现出高达1.1 cm(2)V-1 S(-1)的高电子迁移率，这是因为它克服了PPV中常见的缺陷，如构象无序、弱的链间相互作用和高的LUMO能级。BDPPV代表了第一个在环境条件下可以传输电子超过1厘米(2)V-1 S(-1)的聚合物。
Poly(p-phenylene vinylene) derivatives (PPVs) are one of the most widely investigated p-type polymers in organic electronics. PPVs generally exhibit electron mobilities lower than 10(-4) cm(2) V-1 s(-1), thus hindering their applications in high-performance polymer field-effect transistors and organic photovoltaics. Herein, we design and synthesize a novel electron-deficient PPV derivative, benzo-difurandione-based PPV (BDPPV). This new PPV derivative displays high electron mobilities up to 1.1 cm(2) V-1 s(-1) under ambient conditions (4 orders of magnitude higher than those of other PPVs), because it overcomes common defects in PPVs, such as conformational disorder, weak interchain interaction, and a high LUMO level. BDPPV represents the first polymer that can transport electrons over 1 cm(2) V-1 s(-1) under ambient conditions.
