A red-emitting fluorescent probe has been developed for the selective and sensitive detection of Hg2+. With the addition of Hg2+, the solution of probe 1 displayed a remarkable fluorescence enhancement (102 fold) with λemmax = 625 nm and a large Stokes shift (150 nm). The detection limit of this probe was as low as 7.1 nM based on S/N = 3. This probe exhibited a good performance in detecting Hg2+ in real water samples, living cells and organisms.
一种红色荧光探针被开发出来，用于选择性和灵敏地检测 Hg2+。随着 Hg2+ 的加入，探针 1 的溶液显示出显著的荧光增强（102 倍），λemmax = 625nm，Stokes 位移大（150nm）。该探针的检测限低至 7.1 nM（基于 S/N = 3）。该探针在实际水样、活细胞和生物中检测 Hg2+ 时表现出良好的性能。
