Through this project, jointly funded by the Macromolecular, Supramolecular, and Nanochemistry (MSN) program in the Division of Chemistry (CHE) and the Established Program to Stimulate Competitive Research (EPSCoR) program in the Office of Integrative Activities at NSF, Professor Colleen Scott at Mississippi State University seeks to understand the relationship between the chemical structures and the electron transport process in certain classes of polymeric materials - redox polymers. Redox polymers are polymers containing groups that can be reversibly reduced or oxidized. Professor Scott is interested in understanding how small changes in the structure of these polymers stabilize the reversible electron transfer process (i.e. the redox process) in the materials. The stabilization of the redox process is essential to the longevity of these materials that are used in common everyday devices such as televisions, cell phones, medical devices, etc. The success of this research is fundamental to the advancement of technologies that are used in our daily lives. Additionally, by joining forces with the Ms. Smith Educational Service, a community program focusing on afterschool and summer academic programs, Professor Scott plans to engage K-12 students who are at risk of not completing their primary education. The “Science with Dr. Scott” initiative integrates fun-filled polymer chemistry activities into the learning environment. Such activities engage student curiosity, increase student enthusiasm for science, motivate students to continue with their education, and ultimately create an informed citizenry excited about discovery and innovation.The advancement in the organic device technology relies greatly on the processability, efficiency and stability of the organic materials that comprise the devices. An in depth understanding of the impact of the chemical structures on the electrochemical processes of redox polymers is of utmost importance to the development of durable redox materials. Professor Scott aims to develop processable redox polymers that are electrochemically stable by studying the structure/property relationships of the polymers with respect to their electrical conductance and redox properties. She also provides learning opportunities to undergrad students at Mississippi State University through research experiences and coursework. Additionally, the “Science with Dr. Scott” initiative integrates polymer chemistry activities into the learning environment of K-12 students who are at risk of not completing their primary education.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

通过这个项目，由化学部（CHE）的大分子，超分子和纳米化学（MSN）计划和NSF综合活动办公室的刺激竞争研究（EPSCoR）计划的既定计划共同资助，密西西比州立大学的科琳·斯科特教授试图了解某些类别的聚合物中化学结构和电子传输过程之间的关系。材料-氧化还原聚合物 氧化还原聚合物是含有可以可逆还原或氧化的基团的聚合物。Scott教授有兴趣了解这些聚合物结构的微小变化如何稳定材料中的可逆电子转移过程（即氧化还原过程）。氧化还原过程的稳定性对于这些材料的寿命至关重要，这些材料用于电视机，手机，医疗设备等常见的日常设备，这项研究的成功对于我们日常生活中使用的技术的进步至关重要。此外，通过与史密斯女士教育服务，一个专注于课后和夏季学术课程的社区计划，斯科特教授计划从事K-12学生谁是在没有完成他们的小学教育的风险。“与斯科特博士一起科学”计划将充满乐趣的聚合物化学活动融入学习环境。这些活动激发学生的好奇心，提高学生对科学的热情，激励学生继续接受教育，并最终创造出一个对发现和创新感到兴奋的知情公民。有机器件技术的进步在很大程度上依赖于组成器件的有机材料的可加工性，效率和稳定性。深入了解氧化还原聚合物的化学结构对电化学过程的影响对于开发耐用的氧化还原材料至关重要。Scott教授的目标是通过研究聚合物的结构/性能关系，开发电化学稳定的可加工氧化还原聚合物，这些聚合物与其电导和氧化还原性能有关。她还通过研究经验和课程工作为密西西比州立大学的本科生提供学习机会。此外，“与斯科特博士一起科学”计划将聚合物化学活动融入到K-12学生的学习环境中，这些学生面临无法完成小学教育的风险。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
