Synthesis and Characterization of X-azo Dyes (X˭Ni, Cu, Zn) for Digital Versatile Disc-Recordable (DVD-R)

Abstract

Abstract We have synthesized 5-(diethylamino)-2-[(E)-2-(methoxy-1, 3-benzo thiazole)-1-diazenyl] phenol (DMBTA) azo and DMBTA complexed with Ni, Cu, and Zn for DVD-R fabrication. The structures of the products were characterized by 1H-NMR and FT-IR. The properties of the compounds required for DVD-R fabrication were elucidated by UV-VIS and TGA. From the UV-VIS data, Zn-DMBTA exhibited the best response with 635 nm generally used in a DVD player. Based on the analysis of TGA data, it showed high thermal stability. Accordingly, Zn-DMBTA is the best compound as a recording material for DVD-R fabrication.
