A new series of polymers has been discovered based on polyvinylpyridine containing pendent allyl radicals and anions fully substituted with pyridinium cation groups. These "densely charged" polymers show interesting properties. They are remarkably stable. The dry polyallyl anions are not conducting, but the polyradicals have electrical conductivity in the semiconductor range. A new polymeric structure is proposed, which will be prepared and may have interesting conduction and photoconduction properties. The polymers may also have specific ion-exchange properties. The research deals with the preparation and characterization of a number of such polymers with varying degrees of crosslinking. The electrical properties of these polymers will be tested, and an important part of these tests will be their behavior as electrode-coating materials. This grant is being funded under the Materials Chemistry Initiative.

基于含有垂直烯丙基自由基的聚乙烯基吡啶和用吡啶阳离子基完全取代的阴离子，已经发现了一系列新的聚合物。 这些“密集的电荷”聚合物显示出有趣的特性。 他们非常稳定。 干燥的聚丙烯阴离子没有进行，但多自由基在半导体范围内具有电导率。 提出了一种新的聚合结构，该结构将准备，并可能具有有趣的传导和光合作用。 聚合物也可能具有特定的离子交换性能。 该研究涉及许多此类聚合物具有不同程度的交联的制备和表征。 这些聚合物的电气特性将进行测试，这些测试的重要部分将是它们作为电极涂层材料的行为。 该赠款是根据材料化学计划资助的。
