Three novel azo dyes, (2-(4-methyl-2-thiazolylazo)-5-diethylaminophenol,MTADP) and its nickel and zinc chelates have been synthesized. The structures of the compounds are characterized by elemental analysis, MS, FT-IR and FT-Raman spectroscopy. The UV-Vis absorption spectra indicated metal chelation results in about 60~70 nm bathochromic shift of absorption band. Bathochromic shift of Ni-MBADP is about 10 nm larger than that of Zn-MBADP. The decomposition temperature peak is observed at 331℃ for Ni-MTADP and 295℃ for Zn-MTADP by thermo-gravimetric analysis, respectively.
