英文摘要	A new fluorescent chemodosimeter based on tetrahydro[5] helicene imide was synthesized, and it showed high selectivity and sensitivity toward Hg2+ ions over other different tested metal ions in water. The response time was within 0.5 min, and the detection limit of the chemodosimeter for Hg2+ was estimated to be 2.0x10(-8) mol center dot L-1. The Hg2+ promoted deprotection of dithioacetal groups of 1, which induced water-soluble fluorescent chemodosimeter 1 to form a water-insoluble aldehyde precursor.
