Intrazeolite Electron Transfer

这个研究计划资助项目是在材料化学的广泛领域和电化学和多相催化的子领域。 在这18个月的标准补助金的任期内，柯林森教授和她的学生在堪萨斯州立大学将进行沸石内电子转移的基本调查。 特别强调的是将被永久困在沸石框架内的“船在一个瓶”合成产生的电活性分子。 将追求的变量影响内沸石电子转移的系统调查，特别是封装的氧化还原中心的浓度，分布和电子交换速率。 使用一套电化学和光谱探针与合成策略相结合，封装的二价钴和钌的联吡啶络合物的电活性表面浓度和热力学氧化还原性质将作为网站密度，电子交换速率和沸石微环境的函数进行研究。 本研究计划资助项目的目标是表征沸石内电子转移和探索这些独特的有组织的分子组装的实际应用。 该研究对于揭示这些材料在电分析、电催化、电子材料和光学显示等领域的应用具有重要意义。

This Research Planning Grant project is in the broad area of materials chemistry and in the subfields of electrochemistry and heterogeneous catalysis. During the tenure of this eighteen-month standard grant, Professor Collinson and her students at Kansas State University will undertake a fundamental investigation of intrazeolite electron transfer. Special emphasis will be placed on electroactive molecules permanently trapped within the zeolite framework resulting from `ship-in-a-bottle` syntheses. A systematic investigation of variables which influence intrazeolite electron transfer will be pursued, particularly the concentration, distribution, and electron exchange rate of the encapsulated redox centers. Using a suite of electrochemical and spectroscopic probes in combination with synthetic strategies, the electroactive surface concentration and thermodynamic redox properties of encapsulated bipyridine complexes of divalent cobalt and ruthenium will be investigated as functions of site density, electron exchange rate, and zeolite microenvironment. The objective of this Research Planning Grant project is the characterization of intrazeolite electron transfer and an exploration of the practical applications of these unique organized molecular assemblies. This research is important to uncovering applications of these materials in areas such as electroanalysis, electrocatalysis, electronic materials, and optical displays.
