摘要
Hydrazine often receives publicity because it has a wide range of applications but high toxicity at the same time. Here, we invented a novel aldehyde spiropyran fluorescent probe (SP-CHO) for fluorescence determination of hydrazine. The probe was synthesized through a hydrolysis reaction and a condensation reaction. It exhibits a specific response to hydrazine. The influence factors and anti-interference ability of SP-CHO identifying hydrazine were studied. HRMS, 1 H NMR, and density functional theory (DFT) calculations were used to reveal the recognition mechanism. Results showed that SP-CHO can be used for fluorescence determination of hydrazine with high selectivity and sensitivity. An SP-CHO-based fluorescence method was established for quantitation of hydrazine. The detection limit was 1.26 μmol/l, and the linear range was 5-100 μmol/l. The determination of hydrazine in water samples can be completed within 10 min, which shows good application prospects in real-time detection and process monitoring.
