Study Of Asymmetric Metal-Dithiene Complex On Synthesis And Spectroscopic Properties

Nickel-dithiene complexes are a kind of near infrared dyes which have very important application in the laser protection ,electron photography, optical recording and so on.The development of near infrared dyes is introduced in this dissertation briefly .The species of near-infrared absorbents ,the synthetic methods and research on vision of metal-dithiene complex have been specially introduced .Two kinds of metal-dithiene complex were successfully synthesized by an absolute new method in this dissertation. Their structures were characterized by the Infrared Spectrum and ~1HMR Spectrum. And the near infrared absorption performance were tested by the Ultraviolet-Visible-Near Infrared Spectrum device. The results revealed that three compounds showed strong absorbency in the range of 860-900nm wavelength. The TG analysis showed three compounds had good thermo-stability. The solubility measurement indicated they had a good solubility in general solvent. Obviously this kind of nickel-dithiene complexes had the huge application potential.
