C. Michael Elliott of Colorado State University is supported by the Division of Chemistry under the Information Technology Research (ITR) program to study molecular systems that have potential application in developing fundamentally new ways of reading stored magnetic information. New molecules and molecular ensembles that exhibit significant chemical responses to magnetic fields in the form of changed decay kinetics of the transient, photogenerated charge-separated state will be explored to optimize the systems for magnetic field responses. Project goals are: (1) to develop an understanding of how structural features of these new systems are related to the magnetic field dependences of their electron-transfer kinetics, specifically the kinetics of photoinduced charge-separated state formation and recombination, (2) to learn if molecular designs not necessarily closely related in structure to previously discovered assemblies will give similar field dependence kinetic responses, and (3) to investigate whether reverse micelles can serve as satisfactory hosts for these systems. Characterization and analysis of the dyes and materials under study will be carried out using pulsed laser spectroscopy, magnetic field effect experiments, and other standard analytical and materials analysis methods.This research project has clear technological underpinnings, motivated by the potential for the research outcomes to enable development of optically based, magnetic field sensors. Significant practical and economic benefits will result if this work leads to fundamentally new ways of detecting magnetic fields that could be used to read magnetic data.

C.科罗拉多州立大学的Michael Elliott在信息技术研究（ITR）计划下得到化学部的支持，研究分子系统，这些系统在开发阅读存储的磁信息的新方法方面具有潜在的应用。 新的分子和分子系综，表现出显着的化学反应，磁场的形式变化的衰减动力学的瞬态，光生电荷分离状态将被探索，以优化系统的磁场响应。 项目目标是：（1）了解这些新系统的结构特征如何与它们的电子转移动力学的磁场依赖性相关，特别是光诱导电荷分离态形成和重组的动力学，（2）了解在结构上不一定与先前发现的组装密切相关的分子设计是否会给出类似的场依赖性动力学响应，（3）考察反胶团能否作为这些体系的主体。 通过脉冲激光光谱、磁场效应实验以及其他标准分析和材料分析方法，对染料和材料进行表征和分析。该研究项目具有明确的技术基础，其研究成果有可能用于开发基于光学的磁场传感器。 如果这项工作能带来全新的磁场探测方法，并可用于读取磁性数据，将产生重大的实际和经济效益。
