  Studies on Photochromic Mechanism And Applications of Pyrryl Substituted Fulgides

  摘要：

  A series of pyrryl substituted fulgides have been designed and synthesized. Photochromic properties of fulgides have been investigated in various organic solvents. Photochromic mechanism of this kind of fulgides have been studied by means of nanosecond laser flash photolysis technique, both of excited singlet and excited triplet state are involved in the photocyclization process. A sample of optical disk was prepared by spin coating method. Photoinduced electron transfer between pyrryl fulgide and TCNQ has been found and studied by UV-Vis and EPR spectroscopic techniques.

  This invention generally relates to a composition, an apparatus, and a method for authenticating a product. In particular, the invention relates to an ink composition for marking a product with a continuous inkjet printer. The composition includes a visible ink and a UV, visible, and/or IR marker. Marking includes depositing the ink composition on the product with the continuous inkjet printer. A marked product is authenticated with a hand-held apparatus that activates the marker in the mark with UV radiation. Activation of the marker in the mark changes the absorbance/reflectance of visible radiation by the mark without changing the visual appearance of the mark. Authenticity of the product is assessed by a change in absorbance or reflectance of visible radiation by the mark after activation of the mark.
