| Outline of Final Research Achievements |
In this study, in order to develop new high-intensity red fluorescence analysis reagents using fluorescence resonance energy transfer (FRET), we synthesized several BODIPY derivatives linked to tryptanthrin derivatives with a spacer. The BODIPY derivatives are fluorescent dyes having a small change in absorption and fluorescence wavelength depending on the solvent, and the tryptanthrin derivatives are red fluorescent dyes exhibiting solvatochromism in response to the polarity of the solvent.
As a result, it was found that detection of Cu2+, Fe3+, and Al3+ was possible by changing from FRET-on to -FRET-off.
