The highly selective chemosignaling behaviors for hydrazine by a reaction-based probe of dichlorofluorescein and resorufin acetates were investigated. Hydrazinolysis of latent dichlorofluorescein and resorufin acetate fluorochromes caused prominent chromogenic and fluorescent turn-on type signals. The probes selectively detected hydrazine in the presence of commonly encountered metal ions and anions as background. Dichlorofluorescein and resorufin acetates selectively detected hydrazine with detection limits of 9.0 × 10−8 M and 8.2 × 10−7 M, respectively. Furthermore, hydrazine was selectively detected over other closely related compounds, such as hydroxylamine, ethylenediamine, and ammonia. As a possible application of the acetate probes, hydrazine signaling in tap water was tested.
研究了基于反应的二氯荧光素和醋酸间苯二酚探针对肼的高选择性化学信号行为。潜伏的二氯荧光素和醋酸间苯二酚荧光素的肼解作用会产生显著的显色和荧光开启型信号。在常见的金属离子和阴离子作为背景存在的情况下,这些探针可选择性地检测到肼。二氯荧光素和醋酸间苯二酚选择性地检测肼,检测限分别为 9.0 × 10-8 M 和 8.2 × 10-7 M。此外,与其他密切相关的化合物(如羟胺、乙二胺和氨)相比,肼被选择性地检测到。作为醋酸盐探针的一种可能应用,对自来水中的肼信号进行了测试。
