Coordination Chemistry of Catecholate and Semiquinonate Ligands

博尔德科罗拉多大学的Cortlandt Pierpont博士得到了无机、生物无机和有机物计划的支持，研究醌酸盐、半醌酸盐和儿茶酚盐络合物的配位化学。儿茶酚和semiquinonate化学的铂金属将被开发，与氧化还原异构体的金属和quinonate配体之间的电荷分布的变化有关的重点。将研究聚合的奎宁鎓络合物。将研究具有与环共轭的醌官能团的酞菁配体。电子在许多过渡金属离子的醌、半醌和儿茶酚配合物中具有高度的移动的性，从而使这些材料具有不寻常的和未预料到的化学、物理和电学性质。改进对这些材料内的电子电荷的再分布的理解和控制在开发用于微观电子器件的材料中以及在描述生物催化剂的功能的关键方面中以及在发明用于非生物化学过程的改进的催化剂中很可能是重要的。

Dr. Cortlandt Pierpont of the University of Colorado, Boulder is supported by the Inorganic, Bioinorganic and Organometallic Program for research on the coordination chemistry of quinonate, semiquinonate and catecholate complexes. Catecholate and semiquinonate chemistry of the platinum metals will be developed, with an emphasis on redox isomers related by shifts in charge distribution between the metal and the quinonate ligands. Polymeric ruthenium-quinonate complexes will be investigated. Pthalocyanine ligands with quinone functionalities conjugated to the ring will be studied. Novel chemistry of molybdenum-catecholate complexes will be considered.Electrons are highly mobile in many quinonate, semiquinonate, and catecholate complexes of transition-metal ions, giving rise to unusual and unanticipated chemical, physical and electrical properties for those materials. Improved understanding and control of the redistribution of electronic charge within such materials is highly likely to be important in developing materials for use in microscopic electronic devices, as well as in description of critical aspects of the functioning of biological catalysts, and in the invention of improved catalysts for non-biological chemical processes.
