| Abstract | A series of novel 6-(2-substituted-1,3,4-oxadiazol-5-yl)-2-phenylthieno[2,3-d]-pyrimidine fluorescent compounds were obtained by the condensation of 6-(2-methylthio-1,3,4-oxadiazol-5-yl)-2-phenylthieno[2,3-d]pyrimidine with appropriate secondary amines. The structures were characterized by 1R, (1)H NMR, mass, elemental analysis and UV-vis spectroscopy and the fluorescence characteristics were investigated in ethyl acetate and acetone by UV-vis absorption and emission spectra. The absorption spectra and fluorescence characteristics were correlated with substituents of the 6-(2-substituted-1,3,4-oxadiazol-5-yl)-2-phenylthieno[2,3-d]pyrimidine compounds and solvent polarity. The novel compounds also displayed intense blue to yellow-green fluorescence in ethyl acetate and acetone solutions. (c) 2008 Elsevier Ltd. All rights reserved. |
