犹他大学化学系约翰·A·格拉迪斯博士受到无机、生物无机和金属有机化学计划的支持,研究其中SP杂化碳原子链跨越两个过渡金属的络合物。该项目的目标是合成线状SP杂化碳链连接两个过渡金属端基的络合物。在M(CC)NH去质子化后,与金属卤化物的反应将两个金属通过偶数个碳链连接起来,而与配位的一氧化碳反应后,羰基的脱氧将产生一个奇数个碳原子的连接。将设计一系列的准备工作,以生产具有各种碳链长度的必要的金属-聚芳基起始材料。将测定双金属物种的电荷转移和氧化还原化学,以确定链长对络合物结构和电子性质的影响。本次调查的目标化合物包含两种金属,它们通过一条仅由碳原子组成的长链相连。这些链可以充当电子或磁性信息可以从一种金属转移到另一种金属的“导线”。因此,它们可以构成微电子设备的基础,并用于基本了解通过扩展连接单元分离的金属相互影响的程度。
英文摘要
Dr. John A.Gladysz, Chemistry Department, University of Utah, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program, to investigate complexes in which chains of sp hybridized carbon atoms span two transition metals. The objective of the project is to synthesize complexes in which wire-like sp hybridized carbon chains connect two transition metal end groups. After deprotonation of M(CC)nH the reaction with metal halides will link the two metals through an even number carbon chain, while reaction with coordinated carbon monoxide followed by deoxygenation of the carbonyl will yield a link with an odd number of carbon atoms. A series of preparations will be designed to produce the requisite metalla-poly-ynyl starting materials with a variety of carbon chain lengths. The charge transfer and redox chemistry of the dimetalla species will be determined to define the effect of chain length on the structure and electronic properties of the complexes. The compounds targeted in this investigation contain two metals that are linked through a long chain that consists solely of carbon atoms. These chains can serve as 'wires' through which electrons or magnetic information can be transferred from one metal to the other. As such they can form the basis for micro-electronic devices and for the basic understanding of how well separated metals can influence one another through extended linking units.
