Orchestration of Single Molecules for Novel Functions

A01 Prof. Ogawa’s group Synthesis and measurements of molecular composites bearing non-symmetric and/or non-linear single molecule electronic properties We are synthesizing new molecules which possibly have non-linear and non-symmetric single molecule electric properties such as rectification, negative differential resistance, and hysteresis. The measurements are performed by a PCI-AFM technique or a mechanical break junction method with helps of other members of this project. Recent results include: “Switching of single-molecule magnetic properties and observation of carbon-surface supramolecular structures of Tb(III) porphyrin double-decker complexes” by Inose et al., “Design and synthesis of perpendicularly connected metal porphyrin-imide dyads for two-terminal wired single molecular diodes” by Handayani et al., and “Synthesis of metal porphyrin arrays with programmable sequences by consecutive Suzuki coupling reaction and investigation of their physical properties“ by Tamaki et al., and so on.
