项目摘要

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准备共轭聚合物的新方法。该方法涉及直接使用溶液处理单体在底物上材料的固态聚合。将所得聚合物直接固定在包括透明装置电极（例如ITO）的底物上。提出了证明这种固态聚合及其在光学上准备和电活性聚合物的优化。应检查靶向厚度的优质膜所需的参数。预计空气稳定的共轭聚合物具有与当前使用的材料相似的光学和电化学性能。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广泛的纯化。影响是一种准备新的光学和电化学活性聚合物的简单方法，这些聚合物可能可能用于有机光发射器件和电致色素设备。直接在设备电极上制备固定聚合物的好处最终是经济和生态优势，因为使用固态准备的材料制造设备需要更少的步骤。 ****可以扩展固态固定底物方法以制备共轭动力学。这些材料可以可逆地进行组件交换和改组。固态比溶液交换反应的优势在于，可逆和连续的聚合物构成组件交换是可能的。建议检查固态中的交换反应，以证明和优化多个组件交换反应而没有多余的聚合物降解。这将提供连续调整聚合物特性（例如颜色，氧化潜力，TG等）的手段。后聚合。提出了这种后聚合特性调整通过交换单体单位和交叉聚合反应的调整。也将检查使用动态作为自我修复材料。********
