Journal Title:Journal of Chemical, Biological and physical sciences

Salicylaldehyde (1) and 5-bromosalicyladehyde (2) was condensed with series of haloanilines (3a-e) forming Schiff bases (anils, 4a-e, 5a-e) which are characterised by FT-IR and NMR spectroscopy. The absorption and emission spectra of final Schiff bases (4a-e, 5a-e) was recorded. The Schiff base shows maximum absorption at 400 nm and 800 nm. The emission spectra of 4a-e and 5a-e were recorded at 400 nm (as excitation wavelength). The halogen substitution on anils shows blue shift in emission.
