单功能分子为开发新型纳米电子器件提供了巨大的潜力，其功能超越了当今的硅基器件。为了实现单分子电子学，需要开发一种使用单个导电聚合物链将功能分子彼此连接的可行方法。使用扫描隧道显微镜（STM）的尖端引发链聚合的方法对于在指定位置处制造单个导电聚合物链并由此布线单个分子非常有用。这篇专题文章概述了联乙炔化合物的可控链聚合和聚联乙炔链的性质的发展。本文还介绍了“化学焊接”技术的最新研究成果，该技术可使聚丁二炔单链共价连接到单功能分子上。这是推进单分子电子学发展的关键一步。
Single functional molecules offer great potential for the development of novel nanoelectronic devices with capabilities beyond today's silicon-based devices. To realise single-molecule electronics, the development of a viable method for connecting functional molecules to each other using single conductive polymer chains is required. The method of initiating chain polymerisation using the tip of a scanning tunnelling microscope (STM) is very useful for fabricating single conductive polymer chains at designated positions and thereby wiring single molecules. In this feature article, developments in the controlled chain polymerisation of diacetylene compounds and the properties of polydiacetylene chains are summarised. Recent studies of "chemical soldering'', a technique enabling the covalent connection of single polydiacetylene chains to single functional molecules, are also introduced. This represents a key step in advancing the development of single-molecule electronics.
