Photophysics and Photochemistry of Transition Metal Complexes with Applications to Sensors

美国国家科学基金会化学部的无机、生物无机和有机金属化学项目支持弗吉尼亚大学化学系的James N. Demas博士和弗吉尼亚州詹姆斯麦迪逊大学化学系的Ben A. DeGraff博士的工作，他们将探索基于发光金属配合物的传感器和探针的基础和应用方面。具体而言，将以合理的方式设计和合成新的配体，新的金属配合物和新的聚合物支撑物，以获得对发光配合物的光物理和光化学的基本理解，以检查传感器分子与聚合物支撑物之间的相互作用，验证某些假设，并进一步提高传感器性能。根据这项研究的结果，主要研究人员将改进和增强用于测试pH值变化和二氧化碳存在的传感器性能。两所机构的几名本科生将参与这项研究，并与研究生一起接受新发光材料和聚合物支撑的合成、反应性、表征、光化学和光物理学方面的无与伦比的培训。

The Inorganic, Bioinorganic and Organometallic Chemistry Program of the Division of Chemistry, National Science Foundation, supports the work of Dr. James N. Demas of the Department of Chemistry, University of Virginia, and Dr. Ben A. DeGraff of the Department of Chemistry, James Madison University, VA, which will explore fundamental and applied aspects of sensors and probes based on luminescent metal complexes. Specifically, new ligands, new metal complexes, and new polymer supports will be designed and synthesized in a rational manner to gain a fundamental understanding of the photophysics and photochemistry of the luminescent complexes, to examine the interactions between the sensor molecules and polymer supports, to test certain hypotheses, and to further enhance sensor performance.With the results from this study, the principal investigators will improve and enhance sensor performance designed to test for changes in pH and the presence of carbon dioxide. Several undergraduate students will be involved in this study at both institutions, and together with graduate students will receive unparalleled training in syntheses, reactivity, characterization, photochemistry and photophysics of new luminescent materials and polymer supports.
