In order to improve the electrical conductance, the π orbital of the molecule is directly bonded to the metal orbital, because anchoring groups, which were typically used in other studies to bind molecule with metal electrodes, became resistive spacers. Using this direct π-binding, the author has successfully demonstrated highly conductive SMJs involving benzene, endohedral metallofullerene Ce@C82, and nitrogen. Subsequently, the author investigated control of the electrical conductance of SMJs using pyrazine. The nitrogen atom in the π-conjugated system of pyrazine was expected to function as an anchoring point, and two bonding states were expected. One originates primarily from the π orbital, while the other originates primarily from an .n. stateof the nitrogen. Measurements of conductance and .dI/dV. spectra coupled with theoretical calculations revealed that the pyrazine SMJ has bistable conductance states, in which the pyrazine axis is either t | | 出版日期 | Book 2017 | | 关键词 | Single molecular junction; Electron transport; Single molecule spectroscopy; Control of electrical cond | | 版次 | 1 | | doi | https://doi.org/10.1007/978-981-10-4412-0 | | isbn_softcover | 978-981-13-5129-7 | | isbn_ebook | 978-981-10-4412-0Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer Nature Singapore Pte Ltd. 2017 |
