Abstract

Pesticide bromoxynil octanoate is widely used in agriculture but possesses the potential toxicity to both animals and humans. The development of facile and on-site detection method for bromoxynil octanoate is extremely expected. In this work, the first example of fluorescent sensor for on-site examining bromoxynil octanoate in aqueous media was reported based on a pyridine-substituted cyanostilbene macrocycle (PSCM). This fluorescent sensor exhibited strong “turn-on” orange fluorescence on sensing bromoxynil octanoate with high selectivity and sensitivity among a wide range of ions and pesticides. The limitation of detection is 2.1 × 10⁻⁸ M. The study on binding mechanism suggested that bromoxynil octanoate is located in the cavity of PSCM based on π-π and hydrophobic interactions. The application experiments indicated that this fluorescent sensor has the excellent sensing behavior on test papers, four real agriculture samples and simulated water samples, implying the good application potential on facile, simple and on-site detecting bromoxynil octanoate in real environments.

吡啶取代的氰二苯乙烯大环：农药辛酸溴腈的“开启”荧光传感器

辛酸溴硝酯是一种广泛应用于农业生产的农药，对动物和人体都有潜在的毒性。辛酸溴苯乙酯的现场简便检测方法的发展是非常值得期待的。本文报道了基于吡啶取代的氰基苯乙烯大环（PSCM）的荧光传感器在水中现场检测辛酸溴甲腈的第一个例子。该荧光传感器在广泛的离子和农药中表现出强烈的橙色“开启”荧光，具有很高的选择性和灵敏度。结合机制的研究表明，基于π-π和疏水相互作用，辛酸溴甲腈位于PSCM的空腔中。应用实验表明，该荧光传感器在试纸、4种实际农业样品和模拟水样上均具有优异的传感性能，在实际环境中方便、简单、现场检测辛酸溴苯乙酯方面具有良好的应用潜力。

期刊介绍： The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field. Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
