Elucidation of structure - single molecule electric property correlation of functional molecules

我们所做的研究阐明了单分子电子学的结构性质相关性，使单分子的多端连接成为可能。制备了以Zn和Rh-I为中心金属的卟啉-亚胺二元分子，用MCBJ法测定了它们的单分子电子性质，发现Zn分子的整流率明显大于Rh-I分子。在使用单壁碳纳米管作为电极的测量中获得了相同的结果。因此，很明显，尽管许多（n,m）指标的混合物，单壁碳纳米管可以用于多终端布线到单分子电子器件。建立了一种制备各种序列卟啉阵列的新方法。

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.
