| Outline of Final Research Achievements |
We investigated the electron transport and thermal transport property of the single molecule junctions of the pi molecules. For example, we were able to fabricate the highly-conducting molecular circuits based on antiaromaticity. We measured the electron transport property of antiaromatic norcorrole-based Ni(II) complex (Ni(nor)) and porphyrin-based aromatic counterpart (Ni(porph)) using scanning electron microscope (STM). As a result, the electron transport property of Ni(nor) was drastically improved compared with Ni(porph). Single-molecule current voltage measurements and ab initio transport calculations reveal that this results from a reduced energy gap and a frontier molecular resonance closer to the Fermi level in the antiaromatic species. The conductance of the antiaromatic complex is further modulated electrochemically, demonstrating its potential as a high-conductance transistor.
