设计制备了一种三苯胺三唑类荧光增强型硫化氢（H₂S）探针SZJ，通过紫外和荧光分析法对SZJ的光学性质进行探究，并通过元素分析、HR-MS、¹HNMR和用卡¹³CNMR对其结构进行表征。在SZJ （1×10^-5 mol/L）的CH₃CN-H₂O （体积比6∶4，10 mmol/L HEPES，pH=7.4）溶液体系中，SZJ对H₂S展示出优异的选择性、抗干扰性和灵敏度。荧光光谱分析发现，只有在SZJ的溶液体系中加入H₂S （1×10^-4 mol/L）时才显示出极强的黄绿色荧光，加入其他阴离子并无响应。并且探针SZJ可通过裸眼检测水样中的H₂S，具有潜在的应用价值。

SZJ,a triphenylamine triazole-type fluorescence-enhanced hydrogen sulfide (H₂S) probe,is designed and prepared.The optical properties of SZJ are investigated by means of UV and fluorescence analysis,and its structure is characterized through elemental analysis,HR-MS,¹HNMR and ¹³CNMR.In a CH₃CN-H₂O (a volumetric ratio of 6:4,10 mmol·L^-1 HEPES,pH=7.4) solution system of SZJ (1×10^-5 mol·L^-1),SZJ shows excellent selectivity,anti-interference and sensitivity to H₂S.It is found through fluorescence spectra analysis that SZJ shows extremely strong yellow-green fluorescence only when H₂S (1×10^-4 mol·L^-1) is added into the solution system of SZJ,while it does not show response when other anions are added.Furthermore,SZJ probe can detect H₂S in water samples with naked eyes,exhibiting a potential application value.
