Abstract: Department of Chemistry, Jadavpur University, Kolkata-700 032, India E-mail: [email protected] Department of Chemistry, Raja Peary Mohan College, Uttarpara-712 258, Hooghly, West Bengal, India Manuscript received online 15 September 2019, accepted 19 September 2019 A probe 6,6´-((1Z,1´Z)-(((propane-1,3-diylbis(oxy))bis(2,1-phenylene))bis(azanylylidene))bis-(methanylylidene))bis(2- ethoxyphenol) (H2L), is synthesized by the condensation of 2,2´-(propane-1,2-diylbis(oxy))dianiline with 3-ethoxy-2-hydroxybenzaldehyde and characterized by various spectroscopic techniques (1H NMR, FT-IR, ESI-MS etc.), exhibits greenish yellow emission (λem 556 nm) upon binding with Zn2+ ion in H2O-CH3 CN (1:9 v/v, HEPES buffer, pH 7.4) in a mixture of seventeen other biologically important metal ions. The limit of detection (LOD) is 15.5 nM. The 1:1 composition of the complex, Zn2+: L2–, is supported by Job’s plot, ESI-MS and 1H NMR measurements.
