  Thiazole azo dyes with lateral donor branch: Synthesis, structure and second order NLO properties

  摘要：

  Three azo dyes with a thiazole based donor-pi-acceptor structure containing a methoxyphenyl group as the lateral donor branch were synthesized and fully characterized. The formyl azo dye precursor was synthesized using 5-formylaminothiazole derivative as the diazo component and N,N-diethylaninline as the coupling component. Knoevenagel condensation of this precursor with different acceptors, namely, indandione, malononitrile and dicyanovinylindanone afforded the desired nonlinear optical chromophores a-c, respectively.The optical property, thermal stability and second order nonlinear optical activity were evaluated and a single crystal structural characterization was performed for two of the dyes. All nonlinear optical dyes a-c have good nonlinearity and good thermal stability. Compared with dyes a and b, dye c shows more than triple second order nonlinear optical response, the result that makes this molecule an unusual example of asymmetrical 2D charge transfer chromophore.

• Synthesis, Characterization, and Biological Activity of Substituted Thiazole-5-carboxaldehydes and Their Ylidenenitriles Derivatives

  The Vilsmeier-Haack reaction of 2-amino -4-(4-substituted phenyl)-thiazoles 1, in the presence of micellar media, gives formylated derivatives 2, which upon hydrolysis afforded thiazole-5-carboxaldehydes 3. Microwave-assisted Knoevenagel condensation of 3 with active methylene compounds, in the presence of piperidine as catalyst, gives excellent yields of ylidenenitrile compounds 4. The structures of the newly synthesized compounds were established on the basis of elemental analysis, IR, H-1 NMR, and C-13 NMR spectral analysis. All newly synthesized compounds were screened for antibacterial activity using two Gram-positive and one Gram-negative bacterial species and their antifungal activity was screened using two fungal species.
