Patrick E. Hoggard of the University of Santa Clara is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program for research on photoreversible systems. Certain photosensitive systems exhibit the unusual property of switching between two grossly different states (one predominantly product, the other predominantly reactant) on slight perturbation. This is interpreted as indicating that the forward and reverse reactions involve different mechanisms. This phenomenon will be studied in Ru(bpy)2Cl2 systems, and other systems with this property will be sought for.Switching between two states of quite different properties is important in a number of technologically and scientifically important areas. The systems of interest in this proposal involve both photochemical activation and sensitivity to changes in adjustable parameters, such as the nature of the solvent. This research aims at increased understanding of presently known model systems. That increase in understanding may well lead to development of new and useful photochemical systems and devices, as well as to progress in theoretical comprehension.

帕特里克E.圣克拉拉大学的Hoggard得到了无机、生物无机和有机金属化学项目的支持，用于光可逆系统的研究。 某些光敏系统表现出不寻常的性质，在两个完全不同的状态（一个主要是产物，另一个主要是反应物）之间切换轻微的扰动。 这被解释为表明正向和反向反应涉及不同的机制。这种现象将在Ru（bpy）2Cl2系统中进行研究，并将寻找具有这种性质的其他系统。在一些技术和科学重要领域中，在两种性质完全不同的状态之间切换是重要的。该提案中感兴趣的系统涉及光化学活化和对可调节参数（例如溶剂的性质）的变化的敏感性。这项研究旨在增加对目前已知的模型系统的理解。理解的增加很可能导致新的和有用的光化学系统和设备的开发，以及理论理解的进步。
