Three types of black azo-metal complexes were synthesized by chromium chloride linked with the azo complexes,which were prepared by 2-amino-4-nitrophenol,4-tert-amyl-2-amino-6-nitrophenol coupling with 2-naphthol.The chemical structure of azo-metal complexes were characterized by elemental analysis and infrared spectroscopy.Optical-thermal properties of azo-metal complexes were investigated by ultraviolet-visible spec-troscopy(UV-Vis)and thermogravimetric analysis(TGA).Results showed that the elemental compositions and chemical structures of these complexes obtained were the same as that of target compounds,these complexes had good thermal stability,the 5% weight loss temperatures were 358.85 ℃,322.25 ℃,365.14 ℃,respective-ly,and had strong absorption peaks at 550~650 nm.
