π-共轭凝胶在有机电子应用中具有潜在的用途。我们提出了一种π共轭离子凝胶，由取代的聚（对苯撑乙炔）（PPE）和离子液体。这种组合非常适合作为发光电化学电池（LEC）中的活性材料。凝胶的纳米偏析结构实现了聚合物和离子液体（IL）之间的大界面，并允许-通过其结构的性质-容易的离子传导和连续的导电路径。有效的掺杂显著提高了响应时间。这个概念应该适用于其他π-共轭凝胶，它允许构建凝胶-LEC。
π-conjugated gels are potentially useful for organic electronic applications. We present a π-conjugated ion gel, composed of substituted poly(para-phenyleneethynylene) (PPE) and an ionic liquid. This combination is well suited as an active material in a light-emitting electrochemical cells (LECs). The nanosegregated structure of the gels achieves a large interface between the polymer and ionic liquid (IL) and allows—by nature of its structure—facile ion conduction and continuous electrical conduction paths. Efficient doping significantly improves the response time. This concept should be applicable to other π-conjugated gels, and it allows the construction of gel-LECs.
