Novel Transition Metal Liquids and Complexes

化学部无机、生物无机和金属有机化学计划支持内布拉斯加州大学林肯分校化学系Stephen DiMagno博士的研究，开发两类新的可调配体，即β-八氟卟啉和二亚甲基卟啉，这将导致一系列新的具有特殊电子性质的金属卟啉和金属二亚甲基配合物。这是一项涉及合成新配体的新的广泛的研究，将扩大这些配体的种类，并将考察其光谱、光物理、电化学和催化性能。这项工作还将利用配体的构象动力学来同步向金属中心传递氧化还原当量和酸性或碱性官能团。这些研究的结果将对化学的交叉学科做出重大贡献，这些学科对环境、经济和教育问题产生广泛影响。本科生和研究生将在这个最先进的化学领域得到良好的培训。

The Inorganic, Bioinorganic and Organometallic Chemistry Program of the Chemistry Division supports the research of Dr. Stephen DiMagno, Department of Chemistry, University of Nebraska - Lincoln to develop two new tunable classes of ligands, namely the beta-octafluoroporphyrins and the porphodimethenes, which will lead to a new series of metallo-porphyrins and metallo-porphodimethene complexes having unusual electronic properties. The repertoire of these ligand classes will be expanded and the spectroscopic, photophysical, electrochemical and catalytic properties of the resulting metal-chelates will be examined.This is a novel and wide ranging study involving new strategies to synthesize new ligands. The work will also exploit the ligand's conformational dynamics to synchronize delivery of redox equivalents and acidic or basic functionality to the metal centers. Results of these studies will contribute significantly to the interdisciplines of chemistry that broadly impact on environmental, economic and educational issues. Undergraduate and graduate students will get sound training in this state-of-the-art field of chemistry.
