摘要
以4-N,N-二乙基氨基水杨醛为原料,制备了2-(苯并噻唑-2-基)-5-(N,N-二乙基氨基)苯酚衍生物(探针L),并对其结构进行了表征。在DMSO/PBS(体积比3∶7,pH=7.4)溶液中,探针L具有高选择性并可荧光“关-开”识别H2S,在365nm紫外灯照射下,由无荧光变成蓝色荧光。实验表明,探针L识别H2S的检测限为2.05×10^-6mol/L,pH适用范围为6~9,可用于检测实际水样中的H2S。
The 2-(benzothiazol-2-yl)-5-(N,N-diethylamino)phenol derivative(probe L)was synthesized using 4-N,N-diethylamino salicylaldehyde as the starting material,and its structure was characterized.In DMSO/PBS(3∶7,v/v,pH=7.4)solution,probe L can recognize H2S with high selectivity and fluorescence“turn-on”responding,and fluorescence color was changed from non-fluoresce to blue strong fluorescence by irradiation with a 365 nm UV lamp.The experimental results indicated that the detection limit of probe L is 2.05×10^-6mol/L,and the pH range of L recognition for H2S is 6~9.The probe L can be used to detect H2S in real water samples.
