US-Egypt Cooperative Research: Mechanism of Photochromism of Dithizonate Complexes Useful for Commercial Application

描述：该奖项旨在支持乔治亚州亚特兰大市乔治亚理工学院化学与生物化学系Mostafa El-Sayed博士与埃及开罗国家研究中心无机化学系Mohamed F. R. Fouda博士之间的合作项目。他们计划研究双硫腙配合物光化学转化现象的分子机制。他们计划合成过渡金属的一级和二级配合物以及有机汞化合物，并利用光学和红外瞬态激光光谱在飞秒到秒的尺度上跟踪光化学转化。在光致变色过程中形成的不同中间体的电子吸收光谱和振动吸收光谱及时地跟踪了它们的形成和衰减时间。将考察激发波长、温度和溶剂（包括不同的聚合物）的影响。项目范围：该项目支持两位经验丰富的研究者之间的合作。El-Sayed教授是世界知名的激光光谱学和飞化学专家。Fouda博士在双硫腙配合物的合成和性能方面拥有丰富的经验。这些配合物具有非常重要的光致变色性能，是重要的商业和工业应用材料。这些化合物的合成将在开罗的NRC进行，而光谱研究将在佐治亚理工学院进行。该项目将包括两位科学家和一名来自埃及的研究生。这三人将在项目的三年里每年交换一次访问。该提案符合INT在共同感兴趣的领域支持合作研究的目标。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。

0112607ElsayedDescription: This award is to support a collaborative project between Dr. Mostafa El-Sayed, Department of Chemistry and Biochemistry, Georgia Institute of Technology, Atlanta, Georgia and Dr. Mohamed F. R. Fouda, Department of Inorganic Chemistry, National Research Center, Cairo, Egypt. They plan to study the molecular mechanism of the phenomena of photochemical transformations in dithizone complexes. They plan to synthesize transition metal primary and secondary complexes as well as organo-mercuric compounds, and follow the photochemical transformations on the femtosecond-to-second scale by the use of optical and infrared transient laser spectroscopy. The formation and decay times of the different intermediates formed during the photochromic process will be followed in time from their electronic and vibration absorption spectra. The effect of the exciting wavelength, temperature and solvent (including different polymers) will be examined. Scope: The project supports collaboration between two very experienced investigators. Professor El-Sayed is a world-renowned expert in laser spectroscopy and in femtochemistry. Dr. Fouda has excellent experience in dithizone complexes synthesis and properties. These complexes have very important photochromic properties and represent important materials of commercial and industrial applications. The synthesis of the compounds will be made at the NRC in Cairo while the spectroscopic studies will be carried out at Georgia Tech. The project will include the two scientists and a graduate student from Egypt. Visits by these three will be exchanged in each of the three years of the project. The proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
