A new zwitterionicconjugatedpolyelectrolyte without free counterions has been used as an electroninjection material in polymerlight-emittingdiodes. Both the efficiency and maximum brightness were considerably improved in comparison with standard Ca cathode devices. The devices showed very fast response times, indicating that the improved performance is, in addition to hole blocking, due to dipoles
一种新型的没有游离抗衡离子的两性离子共轭聚电解质已被用作聚合物发光二极管中的电子注入材料。与标准 Ca 阴极设备相比,效率和最大亮度都得到了显着提高。这些器件显示出非常快的响应时间,表明除了空穴阻挡之外,由于阴极界面处的偶极子促进了电子注入,性能得到了提高。

A method of forming a crosslinked polymer and an anion, the method comprising the step of reacting a first polymeric substituent comprising a nucleophilic group and a second polymeric substituent comprising an electrophilic group wherein the first polymeric substituent is a substituent of a first polymer and the second polymeric substituent is a substituent of the first polymer or a second polymer. The first and second polymers may be non-conjugated or conjugated. The crosslinked polymers may be used in electrochemical devices, for example battery cells.
A semiconductive hole transport material containing polar substituent groups, the polar substituent groups substantially not affecting the electronic properties of the hole transport material and the hole transport material being soluble in a polar solvent.
