在过去的二十年里，人们对具有特殊固态性质的有机电荷转移(CT)盐的合成和表征的兴趣有增无减。金属导电性和超导性是在这些材料中发现的最迷人的现象，最近也引起了人们对CT盐可以显示出的新颖的磁性和光学性质的关注。这是一个多学科的领域，挑战合成化学家、结晶学家、应用物理学家、理论家和材料科学家的技能。研究这些奇异材料背后的动机有两个：(I)有大量的基础固态化学和物理有待发现，(Ii)在分子电子设备领域有许多潜在的深远的技术应用。导电聚合物(如聚乙炔和聚噻吩)也是如此，这两个领域(CT盐和导电聚合物)的进展基本上是齐头并进的。在这里，我们关注的是作为电子导体的CT盐，我们将重点介绍一些目前处于关注前沿的材料。绝大多数工作都涉及到对单晶的研究。然而，朗缪尔-布洛杰特薄膜材料的创新成果正在涌现。因此，现在正是将这次审查的很大一部分时间用于这一新领域的时候。这篇文章是由一位化学家撰写的，因此，研究这一主题的方法将不同于研究相同材料的另一学科的科学家的方法。几篇评论文章，书籍，2和详细的会议记录
The past two decades have witnessed unabated interest in the synthesis and characterization of organic charge-transfer (CT) salts that display unusual solidstate properties. Metallic conductivity and superconductivity are the most glamorous phenomena to have been discovered in these materials, and recently attention has also been directed to the novel magnetic and optical properties which CT salts can display. This is a multi-disciplinary field that challenges the skills of synthetic chemists, crystallographers, applied physicists, theoreticians, and materials scientists. The motivation behind research on these exotic materials is twofold:(i) there is a wealth of fundamental solid-state chemistry and physics to be uncovered and (ii) there are potentially many far-reaching technological applications within the arena of molecular electronic devices. The same is true of conducting polymers (eg polyacetylene and polythiophene) and progress in the two areas (CT salts and conducting polymers) has largely gone hand-in-hand. Herein, we are concerned with CT salts that are electronic conductors and we will highlight some of the materials that are currently at the forefront of attention. The vast majority of work has involved studies on single crystals. However, innovative results are emerging with Langmuir-Blodgett film materials. It is, therefore, timely to devote a significant part of this review to this new area. This article is written by a chemist, and the approach to the subject will, therefore, be different from that of a scientist from another discipline studying the same materials.
