  1. Chemical Wiring and Soldering toward All-Molecule Electronic Circuitry Masakazu Aonoet al., J. Am. Chem. Soc., 2011, 133 (21), 8227 Tobe Lab. Daichi Ando

  2. Contents Introduction Single-molecule electronics Linear chain polymerization Purpose of this work Result and discussion Adsorption of CuPc Chemical Sodering Conclusion

  3. Single-Molecule Electronics Rectification = 整流性 Díez-Perez, I.; Tao, N. Nat. Chem. 2009, 1, 635–641. Barner, J.; Rabe, J. P. Macromol. Rapid Commun. 2010, 31, 362–367.

  4. Linear chain polymerization Okawa, Y.; Aono, M. J. Chem. Phys. 2001, 115, 2317–2322.

  5. Purpose of This Work Monomer molecules of the diacetylene form a self-assembled monolayer(SAM). Stimulation from the STM tip initiates the chain polymerization of the diacetylene (PDA). The lifted-up structure of PDA enables the reactive end to approach the adsorbed molecule.

  6. Adsorption of CuPc 10, 12-nonacosadiynoic acid (diacetylene molecule) Cupper Phthalocyanine (CuPc)

  7. Chmical Soldering About 70% of the STM images showed type A.

  8. The Density-functional First-Principles Method

  9. The Calculated Distribution sp3 sp sp sp sp sp sp2 sp2 sp2 sp2

  10. Polarons and Bipolarons unpaired electron positive charge polaron bipolaron

  11. PDA-ZnPc-PDA System

  12. Contents

  13. Conclusion ・Conductive polymer nanowires connect to a functional molecule via covalent bonds. ・Polymer connection to phthalocyanine (chemical soldering) is the main reaction. ・This method represents a key step in advancing the development of future single-molecule circuits.
