Abstract : Donor acceptor chromophores were prepared by Knovenagel reaction of 1,3-diethyl-2-thiobarbituric acid with corresponding aldehydes in ethanol using pyridine as catalyst. The structures of newly synthesized compounds were evaluated by FT-IR, H-1 NMR, C-13 NMR, MS spectroscopy and purity of the compounds were confirmed by elemental analyses. The nonlinear refractive index n(2) and nonlinear absorption coefficient beta are measured for these dyes using the closed and open aperture z-scan technique with a cw He-Ne laser at 632.8 nm. These values are found to be high and linearly dependent on the concentration
