- •
New fluorescent sensor 2 based on oxadiazole and phosphonic acid was designed.
- •
The novel sensor 2 was shown to selectively recognize Fe3+ cations.
- •
Competition experiments indicate the sensor 2 can discriminate between mixtures of metal ions.
- •
The recognition mechanism of the sensor 2 toward Fe3+ was evaluated by FTIR.
