Connecting single conductive polymers to a single functional molecule

We have developed a method using a scanning tunneling microscope (STM) probe tip to control the chain polymerization of diacetylene compounds in a self-ordered layer, thereby creating conjugated polydiacetylene nanowires. When a small amount of phthalocyanine was deposited on a molecular layer of diacetylene compound, we found adsorbed and stabilized phthalocyanine single molecules. The initiation of chain polymerization on the diacetylene molecular row to which the single phthalocyanine molecule was adsorbed was also demonstrated.
