Abstract | The invention belongs to the technical field of functional materials and fluorescence detection, and particularly relates to application of a boric acid functionalized lanthanide metal organic framework BA-Eu-MOF in detection of flavone glycoside. According to the invention, strong red light is emitted at 620 nm through the antenna effect and the emission of 3, 5-dicarboxyphenylboronic acid sensitized Eu < 3 + >. A cis-diol structure contained in glycosyl on flavonoid glycoside reacts with a boric acid group on BA-Eu-MOF to form cyclic borate, the fluorescence intensity of BA-Eu-MOF at 620 nm is weakened through an inner filter effect and photoelectron transfer, and the fluorescence intensity of BA-Eu-MOF is changed, so that the fluorescence intensity of BA-Eu-MOF at 620 nm is changed, and the fluorescence intensity of BA-Eu-MOF at 620 nm is changed. A sensing platform of six flavone glycosides including baicalin, quercitrin, wogonoside, astragalus smicus glycoside, puerarin and rutin is constructed. The dete |
