摘要

以叠氮基为识别基团,合成和表征了一种苯并噻唑类荧光增强型硫化氢探针(FL),并研究了它的光谱性质. 实验结果表明,FL对硫化氢有较高的选择性和灵敏度,且响应快速,抗干扰能力强,细胞毒性低,它的检出限度为8.78×10-7 mol·L-1,在HeLa活细胞和各种水体样品中对硫化氢的检测表明FL具有潜在的应用价值.

Abstract

A benzothiazole-derived fluorescence enhancement probe (FL) for the detection of H2S was synthesized and characterized by employing azide group as the recognition unit, and its spectral properties had been researched. The results showed that FL exhibited relatively good sensitivity and selectivity to H2S as well as fast response, it also had strong anti-interference ability and low cytotoxicity, the detection limit of H2S was estimated to be 8.78×10-7 mol·L-1, and the detection of H2S in living HeLa cells and various water samples indicated that it had potential application value.
