9703311 Lonergan The research program in this CAREER award targets the development of a new concept in conjugated polymer interfaces: the use of conjugated ionomers to form stable interfaces between dissimilarly doped conjugated polymers. The realization of this concept will open a new avenue in the study of conjugated polymer interfaces. An avenue that has great promise for the fundamental study ofthe electronics of conjugated polymers at interfaces and that may lead to a number of exciting new device technologies. The research program has three major elements: (1) a synthetic effort to develop ring-opening polymerization techniques for the synthesis of conjugated ionomers with a controlled density of ionizable functionalities, (2) the development of innovative doping methodologies for the preparation of truly self-doped polymers and for the preparation of multilayer structures in which each layer has different doping characteristics, and (3) the fundamental study of interfaces between differentially doped conjugated polymenrs, such as the polymeric pn junction, to test traditional models of current flow and depletion at semiconductor interfaces. In this CAREER award, activities in support of chemical education at a variety levels are also detailded. At the undergraduate level, a program of implementing tested innovations into the general chemistry curriculum at the University of Oregon is described; these include an emphasis on the concepts of learning through inquiry and of learning from peers. The goal is to better involve students in their own education and go beyond the facts of science to teach how science is done. On the graduate level, the projects works toward improving Oregon's ability to better meet the educational and career goals of individual students while maintaining the scientific rigor and high standards befitting an Advanced degree in chemistry. %%% The primary outcomes of this work will be: (1) self-doped polymers where the leve l of injected charge is precisely balanced by the density of covalently bound ionic centers, (2) a general approach to all polymeric pn junctions and other device structures involving contacted differentially doped conjugated polymers, (3) a systematic study of depletion in conjugated polymers, and (4) a clearer picture of the promise for conjugated polymers in semiconductor device applications. ***

小行星9703311 该CAREER奖的研究计划旨在开发共轭聚合物界面的新概念：使用共轭离聚物在不同掺杂的共轭聚合物之间形成稳定的界面。 这一概念的实现将为共轭聚合物界面的研究开辟一条新的途径。 这是一条很有前途的研究共轭聚合物界面电子学的基本途径，并可能导致许多令人兴奋的新器件技术。 该研究计划有三个主要内容：（1）开发开环聚合技术以合成具有受控密度的可电离官能团的共轭离聚物的综合努力，（2）开发用于制备真正自掺杂的聚合物和用于制备其中每层具有不同掺杂特性的多层结构的创新掺杂方法，以及（3）差异掺杂共轭聚合物之间的界面（例如聚合物pn结）的基础研究，以测试半导体界面处的电流流动和耗尽的传统模型。 在这个CAREER奖中，还详细介绍了支持各级化学教育的活动。 在本科阶段，在俄勒冈州大学的普通化学课程实施测试的创新方案进行了说明，其中包括强调通过调查和从同行学习的概念。 目标是更好地让学生参与自己的教育，超越科学的事实，教授科学是如何完成的。 在研究生阶段，这些项目致力于提高俄勒冈州的能力，以更好地满足个别学生的教育和职业目标，同时保持科学的严谨性和高标准，适合化学高级学位。 %这项工作的主要成果将是：（1）自掺杂聚合物，其中注入电荷的水平通过共价键合的离子中心的密度精确平衡，（2）所有聚合物pn结和其它涉及接触的差异掺杂共轭聚合物的器件结构的一般方法，（3）共轭聚合物中耗尽的系统研究，以及（4）更清楚地了解共轭聚合物在半导体器件应用中的前景。 ***
