Research Abstract

We developed a novel method for single-molecule wiring, which we call "chemical soldering." In this method, a single conductive polymer nanowire is fabricated by initiating a chain polymerization by stimulation with a tip of scanning tunneling microscope. Since the front edge of chain polymerization has a reactive chemical species, when the chain propagation encounters an adsorbed single functional molecule, a covalent bond will be formed spontaneously. This result would be a key step in advancing the development of single-molecule device circuits.
