This renewal project, supported in the Analytical and Surface Chemistry Program, focusses on the synthesis and characterization of metal containing polymers that exhibit novel electron transfer and electrocatalytic properties. Professor Elliott and his students at Colorado State University will pursue work in four areas. The development of electrochemical methods to directly measure the flux of ions in conducting polymers, the use of impedance measurements to evaluate a polypyrrole system as a sensor for chlorocarbons, preparation of fixed redox gradients in polymers and of low-work-function conduction properties in polymer films for practical applications as light emitting diodes, and the preparation of metal complexes in polymers that will exhibit enhanced catalytic activity compared with conventional coordination complexes will be pursued. The synthesis of electroactive polymers that have properties permitting their use in diverse practical areas such as chemical sensors, light emitting diodes, and superior metal centered catalysis will be pursued. Professor Elliott and his students at Colorado State University will employ a wide range of techniques in both the synthetic aspects of this work and in the characterization of the newly prepared polymers. There are exciting prospects for these new materials having real value in numerous areas of analysis and synthesis. New electrochemical methods will be developed and a variety of established electrochemical methods will be used in this work.

这一更新项目得到了分析和表面化学计划的支持，重点是合成和表征具有新的电子转移和电催化性能的含金属聚合物。埃利奥特教授和他在科罗拉多州立大学的学生将在四个领域开展工作。将继续开发直接测量导电聚合物中离子通量的电化学方法，使用阻抗测量来评估作为氯碳传感器的聚吡咯体系，制备聚合物中固定的氧化还原梯度和用于实际应用的聚合物薄膜的低功函数导电性能，以及制备将显示出比传统配位络合物更高的催化活性的聚合物中的金属配合物。电活性聚合物的合成将被用于各种实用领域，如化学传感器、发光二极管和高级金属中心催化。埃利奥特教授和他在科罗拉多州立大学的学生将在这项工作的合成方面和新制备的聚合物的表征方面采用广泛的技术。这些新材料在许多分析和合成领域具有真正的价值，具有令人兴奋的前景。将开发新的电化学方法，并将在这项工作中使用各种现有的电化学方法。
