US-France Cooperative Research: Controlled Optoelectronic Properties of Hybrid Dioxythiophene Polymers

在这个为期三年的美法合作研究项目中，佛罗里达大学的John Reynolds和卡尚高等师范学院的Pierre Audebert的研究小组将研究开发新的基于双氧杂环的杂化共轭聚合物。美国团队在二氧噻吩和二氧吡咯聚合物系统方面具有专业知识。此外，法国还专门研究四嗪、三嗪和环烷系统。目的是研究这些聚合物体系的光电性能和氧化还原性能。有针对性地研究了n型掺杂、多色电致变色、电致变色/光致变色复合材料、可控发光等可能具有特殊影响的四种特性。法国实验室提供了光致变色和荧光实验仪器。该项目将促进我们对聚合物设计的理解，并有可能导致新的电致变色/光致变色材料在光学和电子领域的应用。美国学生将接受国际研究方面的培训，并有机会在职业生涯早期建立国际研究联系。该项目由美国国家科学基金会（NSF）和法国国家科学研究中心（CNRS）共同资助。NSF为研究人员和研究生访问法国提供资金。CNRS将支持法国队访问美国。

0339735Reynolds In this three-year U.S.-France cooperative research project, the research groups of John Reynolds at the University of Florida, and Pierre Audebert at the Ecole Normale Superieure-Cachan will investigate the development of new dioxyheterocycle-based hybrid conjugated polymers. The U.S. team has expertise in the dioxythiophene and dioxypyrrole polymer systems. This is complemented by French specialization in tetrazine, triazine, and cyclophane systems. The goals are to study the optoelectronic and redox properties of these polymer systems. Four properties, which may have special impact, are targeted: n-Type doping, multi-color electrochromism, combined electrochromic/photochromic materials, and controlled luminescence. Instrumentation for photochromic and fluorescence experiments is available in the French laboratory. The project will advance our understanding in polymer design and has potential to lead to new electrochromic/photochromic materials with applications in optics and electronics. U.S. students will be trained in international research and have the opportunity to establish early on in their careers international research connections.This project is jointly funded by the National Science Foundation (NSF) and the Centre National de la Recherche Scientifique (CNRS). NSF provides funds for visits to France by the investigators and graduate students. The CNRS will support visits to the United States by the French team.
