A quantitative study of solvent effects on photo-physical properties of some azo-salicylaldehyde Schiff
Bases ligands, with various substituent and alkyl group, was carried out, at room temperature. The solvatochromic
behavior of these substances and their solvent–solute interactions, both specific and
non-specific, was analyzed using linear solvation energy relationship concept, suggested by Kamlet–
Taft. The ground and excited state dipole moments of these substances and their molecular resonance
structures were also evaluated via solvatochromic shift method.
