An effective fluorescence sensor for herbicide haloxyfop-P-methyl based on cyclic bicyanostilbene imidazole salt
Haloxyfop-P-methyl is a herbicide widely used in agricultural production. However, the lack of facile and on-site detection methods for haloxyfop-P-methyl remains concern. In this work, the first fluorescent sensor for haloxyfop-P-methyl was developed based on a cyclic bicyanostilbene imidazole salt...

520 | |a Haloxyfop-P-methyl is a herbicide widely used in agricultural production. However, the lack of facile and on-site detection methods for haloxyfop-P-methyl remains concern. In this work, the first fluorescent sensor for haloxyfop-P-methyl was developed based on a cyclic bicyanostilbene imidazole salt (CBIS). CBIS has been prepared by “1 + 1″ condensation of a bicyanostilbene imidazole derivative with a chiral (1S, 2S)-cyclohexanediamine derivative in 68% yield. It possesses the weak green fluorescence at 514 nm in aqueous media, but the strong blue fluorescence at 493 nm after sensing haloxyfop-P-methyl. This turn-on fluorescence and blue-shift wavelength is only observed for detecting haloxyfop-P-methyl among various pesticides and ions. The limit of detection is as low as 1.41 × 10−8 M. The binding mechanism is clarified as that haloxyfop-P-methyl is encapsulated in the cavity of CBIS. The fluorescence sensing ability of CBIS is applied to detect the haloxyfop-P-methyl in test papers, the real samples of apples and oranges, and simulated water samples, suggesting the good application prospect for facile and on-site sensing haloxyfop-P-methyl in real samples of fruits and foods. | ||

However, the lack of facile and on-site detection methods for haloxyfop-P-methyl remains concern. In this work, the first fluorescent sensor for haloxyfop-P-methyl was developed based on a cyclic bicyanostilbene imidazole salt (CBIS). CBIS has been prepared by “1 + 1″ condensation of a bicyanostilbene imidazole derivative with a chiral (1S, 2S)-cyclohexanediamine derivative in 68% yield. It possesses the weak green fluorescence at 514 nm in aqueous media, but the strong blue fluorescence at 493 nm after sensing haloxyfop-P-methyl. This turn-on fluorescence and blue-shift wavelength is only observed for detecting haloxyfop-P-methyl among various pesticides and ions. The limit of detection is as low as 1.41 × 10−8 M. The binding mechanism is clarified as that haloxyfop-P-methyl is encapsulated in the cavity of CBIS.

An effective fluorescence sensor for herbicide haloxyfop-P-methyl based on cyclic bicyanostilbene imidazole salt |
abstract |
Haloxyfop-P-methyl is a herbicide widely used in agricultural production. However, the lack of facile and on-site detection methods for haloxyfop-P-methyl remains concern. In this work, the first fluorescent sensor for haloxyfop-P-methyl was developed based on a cyclic bicyanostilbene imidazole salt (CBIS). CBIS has been prepared by “1 + 1″ condensation of a bicyanostilbene imidazole derivative with a chiral (1S, 2S)-cyclohexanediamine derivative in 68% yield. It possesses the weak green fluorescence at 514 nm in aqueous media, but the strong blue fluorescence at 493 nm after sensing haloxyfop-P-methyl. This turn-on fluorescence and blue-shift wavelength is only observed for detecting haloxyfop-P-methyl among various pesticides and ions. The limit of detection is as low as 1.41 × 10−8 M. The binding mechanism is clarified as that haloxyfop-P-methyl is encapsulated in the cavity of CBIS. The fluorescence sensing ability of CBIS is applied to detect the haloxyfop-P-methyl in test papers, the real samples of apples and oranges, and simulated water samples, suggesting the good application prospect for facile and on-site sensing haloxyfop-P-methyl in real samples of fruits and foods. |
