A Fluorescence Quenching Study for the Interaction of 2,6-bis(5-(p-methylphenyl)-1-H-pyrazol-3-yl)pridine with Zn²⁺ Ion

Abstract:

The synthesis of a novel bispyrazole derivative 2,6-bis (5-(p-methylphenyl)-1-H-pyrazol-3-yl) pridine (BMPP) was described and its structure was conforrmed by ¹H NMR, FTIR, MS techniques and elemental analysis. The interactions of Zn²⁺ ion with BMPP were assessed by fluorescence quenching techniques. The results revealed that the quenching effect is resulting from the formation of Zn²⁺-BMPP nonfluorescent complex. The SternVolmer curves suggested that the quenching effect was the static quenching. The main action forces of these reactions was spontaneous, mainly hydrogen bonds and ΔS-driven obtained by using thermodynamic equations.
