A novel probe design of a pyrene‐disulfide molecular assembly has been proposed and its application for the fluorescence turn‐on detection of mercury(II) ions (Hg 2+ ) has been demonstrated. By taking advantage of the pyrene‐assisted efficient photolysis of disulfide bonds, our proposed sensing system exhibits both high selectivity and sensitivity toward Hg 2+ detection with a detection limit of 5 n M (1 ppb) (see figure).
