项目摘要

The Organic Synthesis Program supports Professor Yves F. Rubin of the Department of Chemistry and Biochemistry at the University of California, Los Angeles for his studies of novel tetrathiafulvalene-based two- and three-dimensional charge-transfer materials. Alkyne groups are used to link tetrathiafulvalene (TTF) derivatives into two- and three-dimensional arrays in which both increased side-by-side contacts between molecules and conjugation through the alkyne pi bonds are expected to alter the charge-transfer properties of the TTF moieties. The potential conductivity, superconductivity, and ferromagnetism of these materials will be examined. With support from the Organic Synthesis Program, Professor Yves F. Rubin of the Department of Chemistry and Biochemistry at the University of California, Los Angeles is exploring the synthesis and properties of molecules designed to display unusual physical properties. Working from a basic structural motif in which two adjacent molecules undergo the partial transfer of charge from one molecule to the other, Professor Rubin links the two interacting molecules into a variety of two- and three-dimensional structures. Use of a carbon-carbon triple bond as the linking group facilitates the interaction between the two molecules. The resulting materials are expected to display unusual electrical conductivity and/or superconductivity as well as magnetic properties, offering to shed light on these important phenomena.

有机合成项目支持加州大学洛杉矶分校化学与生物化学系的 Yves F. Rubin 教授对新型四硫富瓦烯基二维和三维电荷转移材料的研究。炔基用于将四硫富瓦烯 (TTF) 衍生物连接成二维和三维阵列，其中增加分子之间的并排接触和通过炔 pi 键的共轭预计会改变 TTF 部分的电荷转移特性。将检查这些材料的潜在导电性、超导性和铁磁性。在有机合成项目的支持下，加州大学洛杉矶分校化学与生物化学系的 Yves F. Rubin 教授正在探索旨在显示不寻常物理特性的分子的合成和特性。鲁宾教授从两个相邻分子经历从一个分子到另一个分子的部分电荷转移的基本结构主题出发，将这两个相互作用的分子连接成各种二维和三维结构。使用碳-碳三键作为连接基团有利于两个分子之间的相互作用。由此产生的材料预计将表现出不寻常的导电性和/或超导性以及磁性，从而为这些重要现象提供线索。
