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

9601048 Meyer该奖项为期三年，部分支持北卡罗来纳大学化学系Thomas J. Meyer博士和北昆士兰詹姆斯库克大学分子科学系F. Richard Keene博士之间的合作研究活动。这笔资金将主要用于支持北卡罗来纳大学的两名研究生每年在基恩博士的实验室度过两个月的旅费。该项目的重点是利用詹姆斯库克大学开发的新技术设计、制备和开发分子系统。新的合成方法允许制备钌配合物结合三种不同的双齿配体。利用涉及三种配体的分离和重叠的电子跃迁，将开发出从紫外线到可见光再到近红外线吸收光的分子。新型色谱协议的合作开发将允许以空间定义的方式制备包含这些天线发色团和能量传递猝灭剂的分子组装，并着眼于光能到化学能转换的实用性。此次合作建立在Keene博士实验室的专业知识基础上，该实验室开发了用于操纵同分异构体八面体配合物的合成技术，而Meyer博士领导的北卡罗来纳小组则拥有分子设计和光物理表征方面的专业知识。这两个小组的优势的结合应该有助于在理解光能转化为化学能方面取得进展。澳大利亚的这项工作得到了工业、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).
