Single Molecule Rectifying Property of Perpendicularly ConnectedPorphyrin-Imide with Controlled Molecular Orientation

摘要

In previous research, perpendicularly connected porphyrin-imide molecule was proposed [1] andhas been confirmed to possess high single molecular rectification performance. However, therectifying direction remained unknown because it was unable to control the orientation of molecule 1(Figure 1) during mechanically controllable break junction measurement due to the symmetricalanchoring groups.
