Paper Abstract

An azo dye, 2-(2-thiazolylazo)-5-diethylaminophenol(TAP), and its cobalt, copper and nickel chelates have been synthesized, which can be used as optical recording materials in DVD-R. The absorption spectra show a great difference in different metal chelates. This may be attributed to the different modes of coordination of metal ions to the azo dye. The structural consideration responsible for the difference are also discussed.
