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

我们开展了这项研究，以澄清单分子电子的结构性质关联，并使单分子的多末端连接成为可能。制备了以锌和Rh-I为中心金属的卟啉酰亚胺二元分子，并用McBj方法测量了它们的单分子电子性质，发现锌分子的整流率明显大于Rh-I分子。在以单壁碳纳米管为电极的测量中也得到了相同的结果。因此，很明显，尽管多个(n，m)指数的混合物可以用于单分子电子的多端子布线，但单壁碳纳米管仍可用于多端子布线。还建立了一种新的制备不同序列的卟啉阵列的方法。

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.
