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.

化学部的无机、生物无机和有机金属化学项目支持内布拉斯加大学林肯分校化学系 Stephen DiMagno 博士的研究，开发两类新的可调节配体，即 β-八氟卟啉和卟啉二亚甲基，这将导致一系列具有不寻常电子特性的新金属卟啉和金属卟啉二亚甲基配合物。这些配体类别的范围将得到扩展，并且所得金属螯合物的光谱、光物理、电化学和催化特性将得到检查。这是一项新颖且范围广泛的研究，涉及合成新配体的新策略。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功能。这些研究的结果将对化学跨学科做出重大贡献，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获得良好的培训。
