| Outline of Final Research Achievements |
Toward single-molecular devices, we have accomplished this study for the purpose of the construction of function-accumulated single-molecular systems by the control of physical properties based on precise molecular design. Completely insulated oligothiophene molecular wires up to 24-mer using the thiophene monomer whose beta positions were spiro-substituted with dialkylfluorene, were successfully isolated, and thiocyanate anchor groups were introduced to their terminal positions to clarify conduction behavior. In addition, we developed tripodal molecules bearing a variety of pi-conjugated groups anchoring to electrodes and elucidated their synergic pi-channel hybridization to gold and graphene electrodes. Furthermore, we succeeded in the control of the type of conduction carrier depending of the anchoring functional groups and thus paved the way for molecular thermoelectric conversion.
