摘　　要：基于卟啉为荧光发色团,以2,4-二硝基苯磺酰氯为识别部分,设计并合成了一种具有较高选择性、高灵敏度的近红外苯硫酚荧光探针,其结构经~1H NMR,IR和HR-MS(ESI)表征。并研究了其荧光性能。结果表明:该探针可快速(90 s)、高选择性地检测苯硫酚,在5×10^(-6)~13×10^(-6)mol·L^(-1)呈良好的线性关系,检出限为61 nm。A kind of near infrared thiophenol fluorescent probe with high selectivity and sensitivity was synthesized, based on the excellent performance of porphyrins fluorescence chromophore, with 2,4-dinitrobenzesulfonyl chloride as recognition part. The structure was characterized by 1 H NMR, IR and HR-MS（ESI）. The fluorescence property was investigated. The results showed that this fluorescent probe exhibited efficent, and sensitive detection for thiophenol, with a good linear relationship in the concentration range of 5×10 -6 ～13×10 -6 mol·L -1 , and the detection limit was 61 nm.
