Discovery of Helical Organic Molecules to Transfer Electron with High Efficiency
- Reactive to Weak Acid-Stimulus and Reversible by Neutralization with Base -

The research group found that organic molecules with helical shape undergo a unique electron-transfer reaction by acid and base stimuli in a reversible way. These molecules have excellent properties to give and accept electrons. This result is expected, and greatly contributes to the development of organic sensor and electronic devices.
