A novel BODIPY-based colorimetric fluorescent sensor with bis[2-(phenylseleno)ethyl]amine as binding site (Se-1) for Hg2+ and Cu2+ has been developed. Se-1 shows high selectivity and sensitivity toward Hg2+ and Cu2+ over alkali and transition metal ions. Se-1shows a significant red-shift in the absorption spectra from 525 to 571nm for Hg2+ and 590nm for Cu2+, which induces color changes from pink...
