• A novel Hg2+ probe based on dansyl and morpholine units was synthesized.
• The probe can detect Hg2+ with fast response time in a wide pH range.
• The probe showed its excellent anti-interference capability.
• The probe can be used in complicated environment samples.
We have developed a novel fluorescent chemosensor (DAM) based on dansyl and morpholine units for the detection of mercury ion with excellent selectivity and sensitivity. In the presence of Hg2+ in a mixture solution of HEPES buffer (pH 7.5, 20 mM) and MeCN (2/8, v/v) at room temperature, the fluorescence of DAM was almost completely quenched from green to colorless with fast response time. Moreover, DAM also showed its excellent anti-interference capability even in the presence of large amount of interfering ions. It is worth noting that DAM could be used to detect Hg2+ specifically in the Yellow River samples, which significantly implied the potential applications of DAM in the complicated environment samples.
