Grant for Exploratory Research: Temperature Hypersensitivityin Photostationary States

本项目由无机化学、生物无机化学和有机金属化学计划资助，旨在探索研究对温度敏感的光静止状态和光振荡系统。研究的基础是观察到在氯仿溶液中，某些二酸双联吡啶Ru(II)络合物在极小的温度范围内从Ru(II)转变为Ru(III)。也有证据表明，在某些条件下，两种氧化态之间存在光振荡。阐明光化学行为的机制是这项研究的主要目标，尽管计划研究其他可能以类似方式表现的化学系统。%这项研究涉及光化学引发的无机反应，如果成功，可能会在“智能玻璃”方面有非常重要的技术应用，即随着温度改变颜色，各种类型的传感器和开关，以及可能用于大容量存储的应用。

This project funded by the Inorganic, Bioinorganic and Organo- metallic Chemistry Program is for exploratory research on temperature-hypersensitive photostationary states and photooscillating systems. The basis of the proposed investigation is the observation that the photostationary state for certain diacidobisbipyridylruthenium(II) complexes switched from Ru(II) to Ru(III) over a remarkably small temperature interval when irradiated in chloroform solution. There was also evidence for a photooscillation between the two oxidation states under certain conditions. Elucidation of the mechanism of the photochemical behavior is a primary objective of the research although plans are outlined to examine other chemical systems that may behave in a similar fashion. %%% This research, which deals with photochemically initiated inorganic reactions, if successful could have very significant technological applications for "smart glass", i.e., changes color with temperature, various types of sensors and switches, and possibly for mass storage applications.
