Abstract
The solvatochromic behaviour of three heterocyclic Schiffbases derived from isonicotinic acid hydrazide (INH) and pyrrole-2-carboxaldehyde (L1), furan-2-carboxaldehyde (L2) and thiophene-2-carboxaldehyde (L3) was studied in nine solvents of different polarities. The electronic transition properties were investigated using the Kamlet-Taft parameters, dielectric function, refractive index function and Catalan parameters. The results indicate that the hydrogen bond acceptor properties of the solvent are more effective in directing the solvatochromic behavior of the Schiffbases.
