Ratiometric Fluorescent Chemosensor for Hg²⁺ Based on Heptamethine Cyanine Containing a Thymine Moiety

Abstract

Based on a T-Hg(2+)-T binding mode, a sensitive ratiometric fluorescent chemosensor for aqueous Hg(2+) was developed with a heptamethine cyanine chromophore containing a thymine moiety.
