Abstract

Two new Schiff base receptors 1 and 2 have been synthesized and characterized by FT-IR, HRMS and ¹H NMR spectroscopic techniques. Both the receptors show large fluorescence enhancement after addition of Al³⁺ which is recognized by calorimetry. Furthermore, the stability constant and the detection limit of the receptor-Al³⁺ complex were found to be 1.41 × 10⁴ M^-1 and 1.59 × 10⁴ M^-1; and 4.79 × 10^-8 M and 8.28 × 10^-8 M for receptors 1 and 2 respectively, concluded through the titration method. Not only this, the synthesized receptors work glowing in physiological pH range. Thus these receptors could be employed for the estimation of Al³⁺ qualitative as well as quantitative.
