Thiophene aldehyde-diamino uracil Schiff base: A novel fluorescent probe for detection and quantification of cupric, silver and ferric ions

Autor: Kamal H. Bouhadir, Hassan H. Hammud, Nada Sonji, Shawky El Shazly, Ghassan Sonji

Publikováno v: Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy. 150

A new Schiff base from the condensation of 5,6-diamino-1,3-dimethyluracil with 5-methylthiophene-2-carboxaldehyde was synthesized. The compound was characterized by spectral data (UV-Vis, IR, (1)H NMR, fluorescence, MS). Ethanolic solutions of the Sc
