| Outline of Final Research Achievements |
Circular polarized light (CPL) is expected to be a nex-generation light source which enables novel important applications. Electrochemiluminescence (ECL) is a light emitting phenomenon induced by electrochemical reaction. On the other hand, DNA complexes can show various function by interacting with other materials.
In this research program, in order to realize CPL device with large g-value, we integrated DNA complex with helical structure into AC driven ECL with quick emission response and high ECL intensity. Namely, we prepared novel DNA/Ru(bpy)32+ film-modified electrode and fablicated AC-operated ECL cell. The ECL properties of the cell was analyzed. As a result, the ECL was obtained from quite high frequency of 10 kHz, enabling quick response time of < 100 μs.
