Thiazole based novel functional colorants: Synthesis, characterization and nonlinear optical studies using picosecond Z-scan technique was written by Singh, Balvant Shyam;Lobo, Hyacintha Rennet;Krishna Podagatlapalli, G.;Venugopal Rao, S.;Shankarling, Ganapati Subray. And the article was included in Optical Materials (Amsterdam, Netherlands) in 2013.Synthetic Route of C15H12N2S This article mentions the following:
Organic push-pull chromophoric system containing thiazole Schiff bases were synthesized from aminothiazole intermediate. These novel chromophores possessed excellent thermal and optical properties with complete transparency in the visible spectral region. Thermogravimetric anal. revealed that all dyes were thermally stable at temperatures above 300 °C. The third-order nonlinear optical studies, performed using the Z-scan technique with ∼2 ps pulses, revealed excellent three photon absorption coefficients/cross-sections combined with reasonably high values of nonlinear refractive index (n2). The solute n2 was of opposite sign compared to that of solvents. To the best of our knowledge, this is the first report of three-photon absorption studies in Schiff base compounds In the experiment, the researchers used many compounds, for example, 4,5-Diphenylthiazol-2-amine (cas: 6318-74-7Synthetic Route of C15H12N2S).
4,5-Diphenylthiazol-2-amine (cas: 6318-74-7) belongs to thiazole derivatives. The thiazole ring has been identified as a central feature of numerous natural products, perhaps the most famous example of which is epothilone.Various laboratory methods exist for the organic synthesis of thiazoles. For example, 2,4-dimethylthiazole is synthesized from thioacetamide and chloroacetone.Synthetic Route of C15H12N2S
