Abstract
A new azo compound, 1-(2-pyridylazo)-2-naphthol, has been prepared and characterized. The synthesized compound shows a very high affinity for aluminium. The complexation reaction of aluminium has been explored by Colorimetry, FT-IR, H-1 NMR, HRMS and fluorescence spectroscopy. The detection limit has been found to be 1.81 x 10(-8) M estimated by the titration method. The turn-on fluorescence behaviour of aluminium interaction with ligand has been found to be so fast (<5 s) that it can be used for its qualitative as well as quantitative estimation.
