| Research Abstract |
We have performed the research to clarify the structure property correlation of single molecule electronics, and to make multi terminal connection to single molecules possible. Porphyrin-imide dyad molecules with Zn and Rh-I as the central metals were prepared and measured their single molecule electronic properties by MCBJ method to find that Zn molecule showed significantly larger rectification ratio than Rh-I molecule. The same results were obtained in the measurements using single walled carbon nanotubes as the electrodes. Thus, it become clear that SWNTs although mixture of many (n,m) indexes can be used for multi terminal wiring to single molecule electronics. A new method to prepare Various sequence of porphyrin arrays also established.
