We developed new reaction-based probes for the dual signaling of fluoride ions. Selective fluoride-assisted deprotection of resorufin nosylate to generate resorufin fluorochrome was used for signaling. Resorufin nosylate exhibited selective colorimetric and fluorogenic signaling of fluoride ions in acetonitrile. The response from sulfide ions was effectively masked by using the TPEN–Cu2+ complex as a source of Cu2+ ions for masking sulfide. Selective optical signaling of fluoride was possible in the presence of commonly encountered anions with a detection limit of 1.9 × 10−6 M.
我们开发了基于反应的新探针,用于氟离子的双重信号传导。我们利用氟辅助选择性脱保护作用,使 Resorufin nosylate 生成 Resorufin 荧光色素。Resorufin nosylate 在乙腈中对氟离子表现出选择性比色和荧光信号。通过使用 TPEN-Cu2+ 复合物作为掩蔽硫化物的 Cu2+ 离子源,有效地掩蔽了硫化物离子的反应。在常见阴离子存在的情况下,可以对氟化物进行选择性光学信号检测,检测限为 1.9 × 10-6 M。
