The proposed research program will examine new methods for preparing conjugated polymers. The method involves the solid state polymerization of materials directly on substrates using solution processable monomers. The resulting polymers are immobilized directly on substrates including transparent device electrodes such as ITO. Demonstrating this solid state polymerization and its optimization for preparing optically and electroactive polymers are proposed. The parameters required for quality films of targeted thickness are to be examined. Air stable conjugated polymers are expected that have similar optical and electrochemical properties to currently used materials. The advantage of the solid state polymerized materials is that their preparation does not require either stringent reaction conditions or extensive purification. The impact is a simple means of preparing new optically and electrochemically active polymers that can potentially be used in organic light emitting devices and electrochromic devices. The benefit of preparing immobilized polymers directly on device electrodes is ultimately both economic and ecological advantages given that fabricating devices using the solid state prepared materials requires fewer steps. The solid state on-substrate method can be extended to prepare conjugated dynamers. These are materials that can reversibly undergo component exchange and shuffling. The advantage of solid state over solution exchange reactions is that reversible and continuous polymer constitutional component exchanges are possible. It is proposed to examine the exchange reactions in the solid state for demonstrating and optimizing the multiple component exchange reactions without unwanted polymer degradation. This would provide the means to continuously tailor the polymer properties such as color, oxidation potential, Tg, etc. postpolymerization. Such postpolymerization property tuning by exchanging monomer units and cross-polymerization reactions is proposed. Using dynamers as self-healing materials will also be examined.

拟议的研究计划将研究制备共轭聚合物的新方法。该方法涉及使用可溶液加工的单体直接在基材上进行材料的固态聚合。所得聚合物直接固定在包括透明器件电极如ITO的基底上。证明这种固态聚合和优化制备光学和电活性聚合物的建议。将检查达到目标厚度的优质薄膜所需的参数。预期空气稳定的共辄聚合物具有与目前使用的材料类似的光学和电化学性质。固态聚合材料的优点是它们的制备不需要严格的反应条件或大量的纯化。这种影响是制备新的光学和电化学活性聚合物的简单方法，这些聚合物可能用于有机发光器件和电致变色器件。直接在器件电极上制备固定化聚合物的益处最终是经济和生态优势，因为使用固态制备的材料制造器件需要较少的步骤。固态衬底法可以扩展到制备共轭动力分子。这些是可以可逆地进行组分交换和改组的材料。固态交换反应优于溶液交换反应的优点是可逆和连续的聚合物构成组分交换是可能的。建议在固态下检查交换反应，以证明和优化多组分交换反应，而不会发生不必要的聚合物降解。这将提供在聚合后连续调整聚合物性能（例如颜色、氧化电位、Tg等）的方法。提出了通过交换单体单元和交叉聚合反应来调节这种后聚合性能。还将研究使用发电机作为自我修复材料。
