分子导线的研究进展

随着电子设备和器件的尺寸越来越小,基于分子的器件研究引起了人们的广泛关注。其中分子导线具有小尺寸、多样性、性能可调等优点,因而被赋予了许多潜在的应用前景。本文总结了分子导线的概念和分类,重点介绍了两端为金属配合物和含Ru-Ru金属键单元的共轭炔基分子导线,并对四硫富瓦烯类分子的独特性质和它在分子导线中的应用进行了简单小结。

Some New Progress on Molecular Wires

With the miniaturization of electronic devices, molecule-based devices have attracted increasing interest. Molecular wires, an essential part of it, have considerable advantages over the traditional wires including their nanoscale size, diversity and tunability, which give them great potential for application. This paper reviews the concept and classification of molecular wires, the recent progress on the conjugated hydrocarbon chains that have either metal coordination compounds at the terminals or the Ru-Ru bonding complexes. Some work on the electrical properties of tetrathiafulvalene (TTF) and its derivatives for molecular wires is also described.
