The results showed that in DMSO/PBS(10 mM, 1:1 (V/V), pH=7.4) solution, probe TZ-1 has high selectivity and can realize fluorescence "off-on" recognition of S_^2- within 3s, the detection limit is 81 μM, and the pH range is 6~12. Under the irradiation of 365nm UV lamp, the fluorescence changes from no fluorescence to orange fluorescence. In addition, the DMSO/PBS solution of probe TZ-1 changed from colorless to light yellow after adding of S_^2-, and S_^2- could be recognized by naked eye. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
