摘要： As an environmental pollutant, mercury ion (Hg2+) cannot be biodegraded, and will accumulate through the food chain and cause damage to human body. Therefore, it is of great significance to develop a simple and effective method for detecting Hg2+. In this paper, a novel triphenylamine derivative Tbia was synthesized by a simple two-step reaction. Tbia can react with Hg2+ specifically in hydroxyethylpiperazine ethane sulfonic acid (HEPES) solution and release the precursor compound with aggregation-induced emission (AIE) properties, which realized recognition of Hg2+ with "off-on" response. Tbia has good selectivity and sensitivity for Hg2+, a wide range of pH, and the detection limit of 63 nmol/L. In addition, Tbia can be prepared into invisible ink and is expected to be used in packaging of anti-counterfeiting. The test paper loaded with Tbia can be used for qualitative or roughly quantitative detection of Hg2+, and Tbia can detect Hg2+ in real water samples as well as image of Hg2+ in living cells.
