Iridium-based lab-on-a-molecule for Hg2+ and ClO- with two distinct light-up emissions.
The nonemissive iridium complex 2 is a lab-on-a-molecule for the highly selective detection of Hg(2+) and ClO(-) among 33 analytes using its oxime residues as reactive units. At pH 5, chemodosimeter 2 responds to Hg(2+) by dehydration, whereas at pH 8, it is oxidized by ClO(-), resulting in 450- and 235-fold emission increases, respectively, at two distinct wavelengths.
