Abstract
A fluorescence adamantane three-dimensional porous organic framework (AdaPOF) was synthesized via a Suzuki coupling reaction. The AdaPOF showed excellent fluorescence performance with a relative high quantum yield and fluorescence stability. Due to its excellent selectivity to tetracycline (TC), a fluorescence sensor based on AdaPOF was constructed for TC determination. The selective sensing mechanism of the AdaPOF towards TC was studied by density functional theory (DFT) calculation experiments. An AdaPOF–based fluorescence method for TC determination was established, with the linear range of 0.1–9.0 μmol/L (R2 = 0.9959) and the limit of detection (S/N = 3) of 43 nmol/L. Moreover, the fluorescence method was used to the determination of TC in aquatic products and the recoveries were ranged from 94.4% to 103.8%. The results obtained by this fluorescence method were consistent with those of the high-performance liquid chromatography (HPLC) method in the TC determination.
