Outline of Final Research Achievements

This research project was at first planned for three fiscal years from 2012 to 2014, but extended for one more fiscal year (2015), because we have found unique rectification properties in nonvolatile memory devices with metallo-supramolecular polymers. As the result, we have achieved to control the direction of current flow in the device by perpendicular alignment of metallo-supramolecular polymers, which are composed of asymmetrical organic modules and Pt(II) ions (ACS Appl. Mater. Interfaces, 2015, 7, 19034-19042).
