Thermal Properties and Characteristics of Thin Layers of Nickel Dithiolene Complexes

Thermal properties of near infra-red-absorbing nickel dithiolene complexes have been examined by thermal gravimetric and differential scanning calorimetry analysis (DSC-TG). The nickel complexes with relatively low melting points gave a DRAW disc with better recording characteristics, when they were used as inhibitors of the photofading of thin layers of cyanine dyes. Thin layers of the nickel complexes on polymethylmethacrylate or glass were formed by spin coating and by the radio-frequency reactive ion plating technique. Their reflectance, absorption spectra and optical recording characteristics have been recorded
