Xiong, Jie published the artcileA highly fluorescent lanthanide metal-organic framework as dual-mode visual sensor for berberine hydrochloride and tetracycline, Synthetic Route of 1455-77-2, the main research area is fluorescent lanthanide metal organic framework sensor berberine hydrochloride tetracycline; Berberine hydrochloride; Dual-mode sensor; Metal-organic framework; Tetracycline; Visual detection.
A microscale highly fluorescent Eu metal-organic framework (Eu-MOF) was synthesized with terephthalic acid and 1H-1,2,4-triazole-3,5-diamine by one-pot hydrothermal method. And it was characterized by scanning electron microscope, FTIR spectroscopy, powder x-ray diffraction, fluorescence spectroscopy, TGA, and energy dispersive x-ray mapping. The prepared Eu-MOF has high quantum yield of 30.99%, excellent water dispersibility, good fluorescence stability, and favorable thermal stability. Based on the distinctly different fluorescence responses of different emission, the prepared Eu-MOF was used as dual-mode visual sensor for the sensitive detection of berberine hydrochloride and tetracycline. The limits of detection are 78 nM and 17 nM, resp. The sensing mechanism is also discussed. Moreover, a filter paper sensor has been designed for sensing tetracycline with a notable fluorescence color change from blue to red. The prepared Eu-MOF is promising to be developed as a multi-mode luminescent sensor for visual detection in biochem. anal.
