A highly sensitive octopus-like azobenzene fluorescent probe for determination of abamectin B₁ in apples.

ABSTRACT: The development of detecting residual level of abamectin B₁ in apples is of great importance to public health. Herein, we synthesized a octopus-like azobenzene fluorescent probe 1,3,5-tris (5'-[(E)-(p-phenoxyazo) diazenyl)] benzene-1,3-dicarboxylic acid) benzene (TPB) for preliminary detection of abamectin B₁ in apples. The TPB molecule has been characterized by ultraviolet-visible absorption spectrometry, ¹H-nuclear magnetic resonance, fourier-transform infrared (FT-IR), electrospray ionization mass spectroscopy (ESI-MS) and fluorescent spectra. A proper determination condition was optimized, with limit of detection and limit of quantification of 1.3 µg L^-1 and 4.4 μg L^-1, respectively. The mechanism of this probe to identify abamecti
