Patents by Inventor Valery Alexandrovich Barachevsky

Valery Alexandrovich Barachevsky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Photochromic monomers, photochromic polymers based on the same, photochromic recording media comprising the photochromic polymers, and 3D read/write optical memory comprising the recording media
    Patent number: 7452950
    Abstract: Photochromic monomers and methods for preparing these photochromic monomers, photochromic polymers based on these photochromic monomers and methods for preparing these photochromic polymers, as well as the use of these photochromic polymers in a polymer binder as a two-photon recording medium for an optical 3D memory and photoswitches of optical signals are disclosed. The materials exhibit thermally irreversible photochromic transformations and other properties enabling the use of the photochromic polymers in an optical two-photon read/write memory.

  • PHOTOCHROMIC MATERIAL AND PROCESS FOR ITS PREPARATION
    Publication number: 20080217590
    Abstract: A curable composition which has photochromic properties and is based on an acrylic compound which can undergo free-radical polymerization, a cured product which is obtained by thermal or photochemical curing of this curable composition on a substrate, e.g. polycarbonate glass with triplex formation (three-layered structure), and a process for the preparation of an optical material are described.

  • Photocontrolled photochromic electroluminescent and electroconductive polymers for photonics
    Patent number: 7297751
    Abstract: The invention relates to photochromic monomers based on benzothiophenes and a method for preparing them, and to photochromic polymers-polyazomethines that are reversibly photocontrollable due to the introduction of photochromic fragments from the class of dihetarylethenes into their structure. The invention provides photochromic photocontrollable polymers for the creation of new information technologies.
