Abstract
We synthesized a novel Schiff-based fluorescent receptor 2, and investigated its binding properties toward various metal ions. The receptor 2 exhibited a blue shift in emission band upon binding with Fe3 +. The receptor 2 exhibited a high association constant with submicromolar detection for Fe3 + in MeOH solution.
Graphical abstract
Receptor 2 exhibits an “off-on-type” mode with high sensitivity in the presence of Fe3 + and a high association constant with submicromolar detection for Fe3 + in MeOH solution.
