Development of a Novel Method for Single Molecule Wiring: Advancing the Realization of Single Molecule Devices

The NIMS International Center for Materials Nanoarchitectonics (MANA), in joint research with other institutions, developed a novel method, "chemical soldering", which enables us to connect single conductive polymer nanowires to individual organic molecules.

Series of scanning tunneling microscope (STM) images demonstrating the chemical soldering to a single functional phthalocyanine molecule. The left image shows phthalocyanine molecules adsorbed on a molecular layer. Chain polymerizations were then initiated to connect one (center image) and two (right image) conductive polymers to a single phthalocyanine molecule. The created polymers are observed as bright lines in the images.

A research teams headed by MANA Scientist Dr. Yuji Okawa and Dr. Masakazu Aono, Director General of MANA (International Center for Materials Nanoarchitectonics) at the National Institute for Materials Science (President: Sukekatsu Ushioda), in joint work with Japan Science and Technology Agency (JST), Universität Basel (Switzerland), Forschungszentrum Jülich (Germany), and University of California at Los Angeles (USA), developed a novel method, "chemical soldering", which makes it possible to connect single conductive polymer nanowires to individual organic molecules. This is a key step in advancing the development of all-molecule electronic circuit, in which each molecule performs the basic functions of electronics.
