| Outline of Final Research Achievements |
Development of novel components for the realization of molecular architectonics has been become a research purpose of this project. In this context, we designed and synthesized new pi-conjugated systems for the use in “anchor” and “insulated molecular wire” units. The tetraphenylmethane-based tripodal structures with thiophene rings as anchoring functional groups were developed to function as hole-transporting anchor units, that is, these molecules fulfill not only the electronic communication between electrodes and molecules but also robust attachment to electrodes with controlling the molecular orientation. Structurally well-defined oligothiophenes were utilized as a key framework of molecular wires. The combination of cyclopenta[c]thiohene with orthogonally introduced alkyl-substituted fluorene substituents accomplished the encapsulation of derived oligothiophene backbones without disturbing effective conjugation, leading to the construction of insulated molecular wires.
