Abstract
In this paper a series of Schiff-bases, synthesized mechanochemically, were studied for their delicate changes in absorption and emission spectra by altering substituents and solvents at different concentrations. UV-vis and photoluminescence of aromatic salicylideneaniline Schiff-base (ASASB) derivatives with substituents ranging from electron donating to electron withdrawing (âCH3, âCl, âBr, âI, âC(O)CH3, âC(O)OC2H5, âCN), and ring nitrogen containing derivatives were studied in solvents of different dielectric constant (n-hexane, toluene, ethyl acetate, THF, ethanol and methanol).
