| Outline of Final Research Achievements |
We proposed a new methodology for one-time and reliable measurement of electric conduction property of a single polymer chain, called molecular grid wiring here, to realize the original motivation of molecular electronic devices. The method replaces the conventional hundreds-to-thousands-times measurement with the nano-gap electrodes by one-time and reliable measurement using a specially fabricated gold nanorod array electrode. The molecular grid wiring is an integrated technique: (1) fabrication of high-density gold nanorod array electrodes, (2) development of surface-initiated/terminated polymerization wiring for pi-conjugated polymers, (3) development of surface-enhanced Raman scattering monitoring of the surface-initiation and surface-terminations of the polymerization wiring, and (4) development of algorithm to derive electric conduction property of a single polymer wire from the gross conductivity.

| Academic Significance and Societal Importance of the Research Achievements |
１個のサイコロを1000回振るのか，1000個のサイコロを一度に振るのか，同じ確率，統計を与えるなら，多数回の測定の代わりに高密度ナノ電極を用いた一回の一括測定に置き換える１分子計測の方法論を提案した．これは，単に１分子伝導の評価だけでなく，分子配線のネットワークを利用した高感度センシングのためのインターフェースとしての応用が期待される．
