拟议的研究计划将研究制备共轭聚合物的新方法。该方法包括使用可溶液处理的单体直接在衬底上进行材料的固态聚合。所得聚合物直接固定在衬底上，包括透明器件电极，如ITO。在此基础上，提出了制备光学和电活性聚合物的固相聚合及其优化方法。应检查目标厚度的优质薄膜所需的参数。空气稳定的共轭聚合物有望具有与当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既不需要苛刻的反应条件，也不需要广泛的纯化。这种影响是一种简单的方法，可以制备新的光学和电化学活性聚合物，这些聚合物可能会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好处归根结底是经济和生态方面的优势，因为使用固态制备材料制造器件需要的步骤更少。固相在基法可以推广到共轭发电机的制备。这些材料可以可逆地进行组分交换和洗牌。与溶液交换反应相比，固态反应的优点是可以进行可逆的和连续的聚合物组成成分交换。建议考察固体状态下的交换反应，以演示和优化多组分交换反应，而不会产生有害的聚合物降解。这将提供持续调整聚合物性能的手段，例如颜色、氧化电位、玻璃化转变温度等。提出了通过交换单体单元和交叉聚合反应来调节后聚合性能。使用发电机作为自我修复材料也将被研究。

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.
