U.S.-Australia Cooperative Research: Chromophore-Quencher Complexes for Studies in Photochemical Redox Splitting

小行星9601048 该奖项为期三年，部分支持北卡罗来纳州大学化学系的托马斯J.迈耶博士和F.北昆士兰州詹姆斯库克大学分子科学系的理查德·基恩说。 这些资金将主要用于支持两名来自北卡罗来纳州的研究生每年在基恩博士的实验室度过两个月的差旅费。 该项目的重点是利用新技术设计、制备和开发分子系统 在詹姆斯库克大学。 新的合成方法允许钌配合物的制备纳入三个不同的双齿配体。 使用涉及三个配体中的每一个的单独和重叠的电子跃迁，将开发出吸收从紫外线到可见光和近红外线的光的分子。 新型色谱协议的合作开发将允许以空间限定的方式制备将这些天线发色团和能量转移猝灭剂并入的分子组件，着眼于光到化学能量转换的实用性。 合作建立在 Keene博士的实验室开发了用于操作同分异构八面体络合物的合成技术，Meyer博士领导的北卡罗来纳州小组具有分子设计和物理表征方面的专业知识。 这两个小组的优势相结合，应该有助于理解光转化为化学能的进展。 澳大利亚的工作得到了工业、科学和旅游部的支持。

9601048 Meyer This award, for a duration of three years, partially supports a cooperative research activity between Dr. Thomas J. Meyer of the Department of Chemistry at the University of North Carolina and Dr. F. Richard Keene of the Department of Molecular Sciences at James Cook University of North Queensland. The funds will primarily be used to support the travel expenses yearly for two graduate students from the University of North Carolina to spend two months in Dr. Keene's laboratory. The project focus is the design, preparation and exploitation of molecular systems which take advantage of new techniques developed at James Cook University. The new synthetic methodology allows the preparation of ruthenium complexes incorporating three different bidentate ligands. Using separate and overlapping electronic transitions involving each of the three ligands, molecules will be developed which absorb light from the UV through the visible and into the near-infrared. The collaborative development of novel chromatographic protocols will allow the preparation of molecular assemblies incorporating these antenna chromophores and energy transfer quenchers in a spatially defined manner, with an eye toward practicality in light to chemical energy conversion. The collaboration builds upon the expertise of Dr. Keene's laboratory which has developed synthetic techniques utilized in the manipulation of isomeric octahedral complexes and the North Carolina group under Dr. Meyer with expertise in molecular design and photophysical characterization. The combination of the two group's strengths should contribute to advances in understanding the conversion of light to chemical energy. The work in Australia is supported through the Department of Industry, Science and Tourism (DIST).
