以3-(2-苯并噻唑基)-2-羟基-5-甲基苯甲醛为原料,合成了一种基于苯并噻唑类衍生物的荧光探针2-(4-叠氮苄氧基)-3-(2-苯并[d]噻唑基)-5-甲基苯甲醛(HBTA),表征了其结构,研究了HBTA对H2S的识别性质.实验结果表明,HBTA在水溶液中(Tris-HCl 0.01 mol·L-1,pH=7.4,含0.005 mol·L-1 CTAB)对H2S具有良好的选择性和灵敏度,且响应快速,抗干扰能力强,并且在较宽的pH范围内有较好的荧光响应,其检测限为9.09×10-7 mol·L-1.细胞成像实验表明,HBTA可用于检测细胞内的H2S.

A new benzothiazole-derived fluorescence probe 2-(4-azidobenzyl)oxy-3-(benzo[d]thiazol-2-yl)-5-methylben-zaldehyde (HBTA) was synthesized from 3-(benzo[d]thiazol-2-yl)-2-hydroxy-5-methylbenzaldehyde, and the structure of HBTA was characterized. The recognition behaviors of HBTA to H2S were investigated and the results show that HBTA exhibits good selectivity and sensitivity to H2S with fast response and good anti-interference ability. The probe can be applied to detect H2S in a broad pH range, and the detection limit of HBTA for H2S was estimated to be 9.09×10-7 mol·L-1. Cell imaging studies reveal that HBTA is capable of detect H2S in live cells.
