U.S.-Hungary Research on Photochemistry and Photophysics of Copper (I) Complexes in Solution

美国和匈牙利对“溶液中铜(I)配合物的光化学和光物理”的研究是由普渡大学的Kenneth L. Stevenson博士和Veszprem大学的Attila Horvath博士和Otto Horvath博士共同完成的。这项工作将研究(1)光解铜的水合电子清除机制(1)与光环、假光环和胺配体配合物的配合物，以及(2)这些配合物和其他配位金属的类似配合物的发光和外络合物形成的机制。该研究将利用紫外可见吸附和发光光谱，以及Nd-YAG激光在纳秒时间和紫外波长区域的闪光光解。结果将提高我们对无机光化学体系中杂络合物和溶剂化电子的基本行为的理解。铜为水合电子的有效光产生提供了许多可能性，这可以用于某些需要还原剂的化学过程。这项提议的化学研究通过使美国和匈牙利的领先专家在共同感兴趣和能力强的领域结合互补的人才和集中研究资源，实现了推进科学的计划目标。

9302792 Stevenson This U.S.-Hungary research on the "Photochemistry and Photophysics of Copper(I) Complexes in Solution" is between Dr. Kenneth L. Stevenson of Purdue University and Dr. Attila Horvath and Dr. Otto Horvath of the University of Veszprem. This work will examine (1) hydrated electron scavenging mechanisms in the photolysis of copper(I) complexes with halo-, pseudohalo, and amine ligands, and (2) luminescence and the mechanism for exciplex formation in such complexes, and in similar complexes of other coordinating metals. The study will use uv-visible adsorption and luminescence spectroscopy, and Nd-YAG laser flash photolysis in the nano-second time regime and ultraviolet wavelength region. Results should improve our understanding of the fundamental behavior of exciplexes and solvated electrons in inorganic photochemical systems. Copper offers many possibilities for efficient photogeneration of hydrated electrons, which could be used for certain chemical processes requiring reducing agents. This proposed research in chemistry fulfills the program objectives of advancing science by enabling leading experts in the U.S. and Hungary to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
