9302792史蒂文森这项关于“铜(I)络合物在溶液中的光化学和光物理”的美国-匈牙利研究是由普渡大学的肯尼思·L·史蒂文森博士与维斯普雷姆大学的阿提拉·霍瓦斯博士和奥托·霍瓦斯博士共同完成的。这项工作将研究(1)铜(I)与卤素、假卤素和胺配体的络合物光解中的水合电子清除机制，以及(2)此类络合物以及其他配位金属的类似络合物中的发光和激基络合物的形成机制。本研究将利用紫外-可见吸收光谱和发光光谱，以及在纳秒区和紫外区进行激光闪光光解。这些结果将有助于我们更好地理解无机光化学体系中激基络合物和溶剂化电子的基本行为。铜为高效光产生水合电子提供了许多可能性，可用于某些需要还原剂的化学过程。这项拟议的化学研究通过使美国和匈牙利的顶尖专家能够将互补的人才结合在一起，并在相互感兴趣和能力很强的领域汇集研究资源，从而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.
