Orientational Effects in Metal-based Electron Transfers

这项授予加州大学欧文分校的初学者奖金支持帕特里克·J·法默教授的研究。本研究的主题是定向双金属络合物的合成和研究，以阐明长距离电子转移的机理。在具有四胺配体的镍、铜和钴双金属络合物体系中，可以改变两个等价金属中心之间的相对角度，并测量混价氧化态中心之间的电子交换速率，从而可以比较连接性、取向和距离对中心间通信的贡献。这项研究将促进对电子在相对较长距离内传输方式的基本理解。四胺配体在金属基线性聚合物的形成中的使用可能导致具有不寻常的光学和磁性的材料。

This starter grant award to the University of California at Irvine supports the research of Professor Patrick J. Farmer. The theme of the research is the synthesis and study of oriented bimetallic complexes to illucidate the mechanism of long distance electron transfer. In systems of bimetallic complexes of nickel, copper, and cobalt featuring tetra-amine ligands, the relative angle between two equivalent metal sites can be changed and the rates of electron exchange between sites in mixed-valence oxidation states measured, allowing the contributions of connectivity, orientation, and distance to intersite communication to be compared. The research will advance the fundamental understanding of the mode of transmission of electrons over relatively long distances. The use of tetra-amine ligands in the formation of metal-based linear polymers could lead to materials with unusual optical and magnetic properties.
