Stable N-Dopable Organic Polymeric Materials

我们将制备和研究一类广泛的共轭聚合物，它们在掺杂和未掺杂状态下都表现出更好的环境稳定性，并且易于n掺杂。这些聚合物中的一些在加工后具有高强度，同时保留了共轭聚合物的不寻常的电子特性。该类的其他成员将是基于稳定碳的聚电解质。还有一些聚合物是n自掺杂聚合物。这组聚合物有利于导电聚合物的碱掺杂概念的发展，是对聚苯胺祖母绿碱酸掺杂的补充。将采用两种方法：(a)制备聚合物，其中许多氰化物直接附着在主链上；(b)制备聚合物，其中哈克驱动力是主链n掺杂的原理。一旦与Heeger教授在我们研究所的小组合作制备，新的聚合物材料的光学和电子性能将被确定。这些聚合物材料在结构材料、非线性光学衬底、有机发光二极管组件、全聚合物p-n结二极管以及全聚合物电池和高能量密度电池的电池电极等方面具有潜在的应用前景。＊＊＊

9315635 Wudl We will prepare and investigate a broad class of conjugated polymers which should exhibit improved environmental stability in the doped and undoped states and will be easily n-dopable. Some of these polymers, when processed, will have high strength while retaining the unusual electronic character of the conjugated polymers. Other members of the class will be polyelectrolytes based on stable carbanions. Still other polymers will be n-self- doped polymers. This group of polymers lends itself to the development of the concept of base-doping of conducting polymers concept which is complementary to acid doping of polyaniline emeraldine base. Two approaches will be pursued: (a) preparation of polymers where a number of cyanides are directly attached to the backbone and (b) preparation of polymers where a Huckel driving force is the principle for n-doping of the backbone. Once prepared, in collaboration with Professor Heeger's group in our Institute, the new polymeric materials will have their optical and electronic properties determined. These polymeric materials have potential applications as structural materials, as nonlinear optics substrates, as organic light emitting diode components, as all polymer p-n junction diodes, and as battery electrodes for all-polymer batteries and high-energy density batteries. ***
