Widespread application of hydrazine results in serious harm on the natural environments and human health because of its highly toxic, mutagenic, carcinogenic and teratogenic properties. Hence, it is very emergent to develop a convenient and efficient method for detection of hydrazine existed in real environments and living organisms. In this work, a novel ratiometric fluorescent probe PKZ-IN from the natural monoterpenoid 2-hydroxy-3-pinanone was designed and synthesized to detect trace hydrazine. The detection performance of probe PKZ-IN for hydrazine was investigated, and the results showed that this probe possessed excellent performance including large Stokes shift (211 nm), fast response time (<30 s), remarkable emission shift (136 nm), and a wide pH range (5−13). This probe was successfully used to detect hydrazine existed in three different soil samples (humus soil, sandy soil and loess soil). In addition, probe PKZ-IN was also used to prepare nanofibrous membrane for detecting gaseous hydrazine qualitatively and quantitively by the mobile phone platform. Furthermore, PKZ-IN was successfully applied in living organisms and plants imaging for detection of the residual hydrazine.

基于咔唑-嘧啶的新型比率荧光探针，具有大斯托克斯位移，用于检测真实环境和生物体中的肼


肼的广泛应用因其剧毒、致突变、致癌和致畸特性，对自然环境和人类健康造成严重危害。因此，开发一种方便有效的方法来检测真实环境和生物体中存在的肼是非常紧急的。在这项工作中，设计并合成了一种来自天然单萜类 2-羟基-3-松树酮的新型比率荧光探针 PKZ-IN 来检测痕量肼。研究了探针 PKZ-IN 对肼的检测性能，结果表明该探针具有优异的性能，包括大斯托克斯位移 （211nm）、快速响应时间 （<30s）、显著的发射位移 （136nm） 和较宽的 pH 范围 （5−13）。该探针成功检测了三种不同土壤样品 （腐殖质土、沙质土壤和黄土） 中存在的肼。此外，探针 PKZ-IN 还用于制备纳米纤维膜，用于通过手机平台定性和定量检测气态肼。此外，PKZ-IN 已成功应用于生物体和植物成像中，以检测残留的肼。
