Irradiation by light of suitable wavelength and intensity of this photochromic compound induces cleavage of a [C—O] bond of the [1,3]oxazine ring to form a phenolate chromophore.

Reversible coloration of silica or polymeric materials and switching optical signals may involve many cycles of interconversion between different colored states.Type: GrantFiled: August 6, 2010Date of Patent: August 28, 2012Assignee: The University of MiamiInventors: Francisco M.

Publication number: 20120161431Abstract: A method of forming a film of photonic crystal material. A first process is performed upon a material capable of having a photonic crystal structure, this process causing deformation of the material so as to form a film in which incident light received by the material is selectively reflected or transmitted to generate a first optical effect in the film. A second process is performed upon substantially all of the film which applies a shear stress to the film. This causes a change in the material structure so as to generate a second optical effect in the film, different from the first optical effect, in response to incident light. Security films, devices, articles and documents formed using the method are also discussed.Type: ApplicationFiled: July 7, 2010Publication date: June 28, 2012Applicant: DE LA RUE INTERNATIONAL LIMITEDInventors: Günther Vulpius, Götz Peter Hellmann, Peter Wolfgang Andreas Spahn
