abstract {2-(6-ethoxy-2-benzothiazolyazo)-5-diethylaminotrifluoromethane sulfonanilide and its metal (Ni²⁺, Co²⁺, Cu²⁺, Zn²⁺)-azo complexes were synthesized. Their structures were confirmed by elemental analysis, UV-vis absorption spectra, FT-IR, ¹H-NMR and MALDI-MS. Thin films were prepared on K9 glass and polished single-crystal silicon by spin-coating method. The thermal properties of metal complexes were studied by DSC-TGA. The optical constants (complex refractive index N=n+ik) and thickness of the complex thin films on polished single-crystal silicon substrates in the 350 to 800 nm wavelength region have been investigated on an improved rotating analyzer-polarizer type of scanning ellipsometer. Results indicate that the maximal absorption wavelength of metal-azo complexes locate at 621 to 629 nm. The thermal decomposition temperature of the Ni-azo complex is 325°C with a sharp threshold. High refractive index n and low extinction coefficient k are obtained at the recording wavelength of 650 nm. Metal-azo complexes would be promising recording medium candidate for NVD (next-generation versatile disc) with the Super resolution near field structure (Super-RENS) technology.}
