Photochemical and Photophysical Mechanisms of Transition Metal Complexes

加州大学圣巴巴拉分校化学系的Peter C. Ford博士受到无机、生物无机和有机金属项目的支持，研究一些有机金属和过渡金属配位化合物的光化学性质。第一项研究将探索发光化合物的物理和化学激发态失活途径，包括铑胺、乙酰丙酮酸铬衍生物、铜胺和硫代氨基甲酸酯，以及一些包合化合物。将开发相应的理论模型。第二项研究是确定作为激发态反应的主要光产物的短寿命有机金属中间体的化学反应活性。详细研究了三angulo-十二碳羰基三钌(0)和相关烷基炔簇的簇裂。第三个项目是硝普苷的初步光化学研究，重点是亚硝基的释放。激光闪光光解和发光光谱是其中将使用的技术。这些研究将提供激发态过程的机制和动力学的基本信息，这将在无机光化学和更广泛的分子工程中有用。将获得有关金属配合物激发态的定量信息。这项工作涉及非线性光学、光存储器件、光催化和生物医学问题。

Dr. Peter C. Ford of the Chemistry Department, University of California at Santa Barbara, is supported by the Inorganic, Bioinorganic, and Organometallic Program for studies of the photochemical properties of some organometallic and coordination compounds of transition metals. The first study will explore physical and chemical excited state deactivation pathways of luminescent compounds, including rhodium amines, chromium acetylacetonate derivatives, copper amines and thiocarbamates, and some inclusion compounds. Accompanying theoretical models will be developed. The second study is concerned with determining the chemical reactivities of short-lived organometallic intermediates produced as the primary photoproducts of excited stae reactions. The cluster fragmentation of triangulo-dodecacarbonyltriruthenium(0) and a related alkylidyne cluster will be investigated in detail. The third project is an initial photochemical study of nitroprusside, focused especially on the release of nitrosyl. Laser flash photolysis and luminescence spectroscopy are among the techniques which will be used. %%% These studies will provide fundamental information on mechanism and dynamics of excited state processes that will be useful in inorganic photochemistry and more generally in molecular engineering. Quantitative information regarding excited states of metal complexes will be obtained. The work is relevant to nonlinear optics, optical memory devices, photocatalysis, and biomedical problems.
