| Outline of Final Research Achievements |
We synthesized 15 kinds of fluorescent proton sensors and 5 kinds of fluorescent sodium ion sensors having a benzofurazan or an anthracene structure as a fluorophore. Using these novel fluorescent sensors, we measured local ion levels near micelle surfaces. As a result, it was clarified that protons and sodium ions are concentrated near the head groups because of electric interactions in anionic micelles. On the other hand, protons are diluted near the head groups of neutral and cationic micelles due to electric and/or dielectric effects.
