| Research Abstract |
For development of molecular circuits studies on molecular wire and junction based on coordination have been conducted.
Two-dimensional systems based on prophyrin motifs were prepared and their performance based on accumulated pi-conjugated systems has been evaluated. The unique behavior such as switching of luminescence properties by redox processes, tuning of wire-like behavior and QCM properties was observed by analysis of redox properties of the peripheral metal groups and electronic spectra.
Wire-like performance of organic and organometallic molecular wire was evaluated by the STM break-junction method. It has been found that the latter showed performance better than the former presumably because of the relative energetics of the Fermi level of the electrode (Au) and the HOMO level of the molecular wires.
