Seven new azo disperse dyes based on N-benzyl-N-ethyl-aniline were synthesized and characterized by UV-Vis, FT-IR and H-1 NMR spectroscopic techniques. The UV-visible studies and solvatochromic behavior of all dyes in 15 solvents with different polarity were examined and a meaningful correlation was observed. In the optical characterization of dyes using Z-Scan experiment, thin films of polymethyl metacrylate doped with guest synthesized chromophores 2, 3, 4 and 7 were investigated. (C) 2009 Elsevier B.V.
