title: A Novel Coumarin-Based Fluorescent Probe for the Detection of Hydrazine Both in Aqueous Solution and Vapor State.
abstract: A novel coumarin-based fluorescent probe CF was synthesized for the detection of hydrazine both in aqueous solution and vapor state with high sensitivity and selectivity. Upon addition of hydrazine, the solution of probe CF in MeCN-H2O (3/7, v/v, buffered CH3COOH/CH3COONa) at pH 5.0 exhibited a remarkable change in emission color from pale green to light blue, which could be recognized with naked eyes. Applied in weak acid condition, probe CF could detect hydrazine selectively with large amount of unknown environments according to the competing tests. Besides, with the limit of detection 8.32 ppb (2.6 × 10(-7) M), probe CF could well meet the request (10 ppb) of the U.S. Environmental Protection Agency (EPA).
