Synthesis of nickel(II) complexes of α-isoxazolylazo-β-diketones and their absorption of spin-coating films and thermal properties for HD-DVD-R

Three kinds of new nickel(II) complexes of α-isoxazolylazo-β-diketones with blue-violet light absorption were synthesized. Their structures were postulated based on elemental analysis, MS and FT-IR spectra. Smooth films on K9 glass substrates were prepared using the spin-coating method. The absorption properties and thermal stability of these complexes were discussed. The static optical recording test for high density digital versatile disc-recordable (HD-DVD-R) system was also studied.

Graphical abstractThree kinds of new nickel(II) complexes of α-isoxazolylazo-β-diketones with blue-violet light absorption were synthesized. It is found that these nickel(II) complexes had potential application for high density digital versatile disc-recordable (HD-DVD-R) system due to their good solubility in organic solvents, reasonable and controllable absorption spectra, high thermal stability and high reflectivity contrast (>50%).Figure optionsDownload full-size imageDownload as PowerPoint slide
