摘要：

A novel chemosensor based on pyrazole biscoumarin molecule "4-hydroxy-34(4-hydroxy-2-oxo-2H-chromen-3-yl)(1,3-diphenyl-1H-pyrazol-4-yl)methyl)-2H-chromen-2-one" (PBC) was synthesized by a simple method. The chemosensing properties of PBC towards transition metal ions like Cu2+ and Zn2+ by naked eye, UV-Visible and fluorescence spectroscopic methods were described. The PBC solution with Cu2+ and Zn2+ ion showed brown and blue colour respectively. The UV-Visible spectra of PBC with Cu2+ and Zn2+ ions exposed their corresponding absorption maxima. Further, the Job's plot method confirmed the 1:1 and 2:1 stoichiometry of the complex formation between the PBC with Cu2+ and Zn2+ ions respectively. The fluorescence enhancement of PBC on binding with Cu2+ and Zn2+ is due to the inhibition of photo induced electron transfer mechanism. (C) 2015 Elsevier B.V. All rights reserved.
