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、生物无机和金属有机化学计划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络合物的传感器和探测器的基本和应用方面。具体地说，将以合理的方式设计和合成新的配体、新的金属络合物和新的聚合物载体，以获得对发光络合物的光物理和光化学的基本了解，检查传感器分子和聚合物载体之间的相互作用，检验某些假设，并进一步提高传感器的性能。随着这项研究的结果，主要研究人员将改进和提高传感器的性能，以测试pH的变化和二氧化碳的存在。两所大学的几名本科生将参与这项研究，他们将与研究生一起接受新发光材料和聚合物载体的合成、反应性、表征、光化学和光物理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.
