Abstract

A simple Zn(ll)-terpyridine complex was synthesized by the reaction of ZnCl₂ with 4′-(3,4-dimethoxyphenyl)-2,2′:6′,2″-terpyridine ligand (DMTRP) in 1:1 ratio. The synthesized complex was treated as a selective fluorescent probe for pyrophosphate P₂O₇⁴⁻ (PPi) amongst other anions like F¯, Cl¯, Br¯, I¯, AcO¯, CO₃^2¯, NO₂¯, SO₃²¯, H₂PO₄¯, HPO₄¯ etc. A 1:3 binding stoichiometry was found from the job's plot analysis. Further to study the sensing mechanism of the complex, theoretical calculations were carried out. Also from theoretical parameters the reactivity, stability and charges of the terpyridine ligand with its zinc complex was calculated.
