  • Materials, methods, and uses for photochemical generation of acids and/or radical species
    Patent number: 7459106
    Abstract: The present invention provides compounds and compositions, which include: at least one chromophore having strong simultaneous two-photon or multi-photon absorptivity; at least one acid- or radical-generator in close proximity to the chromophore; such that the single- or multi-photon excitation of the chromophore results in the generation of an acid and/or redical that is capable of activating chemistry; and such that compositions of matter based on the componds and compositions of the invention can be photo-patterned by one- or multiphoton excitation.
    Type: Grant

  • Photocleavable DNA transfer agent
    Patent number: 7332477
    Abstract: The present invention provides visible light sensitive and ultraviolet (UV) light sensitive composition for DNA transfer comprising acid sensitive polyacetals developed as DNA/RNA delivery agents, a photoacid generator and optionally a photosensitizer.
    Type: Grant
    Filed: July 2, 2004
    Date of Patent: February 19, 2008
    Assignee: Nitto Denko Corporation
    Inventors: J. Kevin Cammack, Sang Van, Peng Wang
  • Photorefractive composite
    Patent number: 7067230
    Abstract: Polydioxaborine compositions are prepared by intermixing a polydioxaborine and a non-linear optical chromophore. Preferred polydioxaborine compositions are photorefractive and/or photoconductive composites.
    Type: Grant
    Filed: January 14, 2004
    Date of Patent: June 27, 2006
    Assignee: Nitto Denko Corporation
    Inventors: J. Kevin Cammack, Peng Wang, Seth R. Marder, Bernard Kippelen
  • Polydioxaborines
    Patent number: 6916894
    Abstract: Novel polydioxaborines are prepared by polymerizing novel monomers that contain a dioxaborine group. Polydioxaborines are readily soluble, excellent film formers, and have semiconducting properties useful in various applications.

  • Methods for extending amorphous photorefractive material lifetimes
    Publication number: 20040242841
    Abstract: Methods for significantly improving the working lifetime of photorefractive materials and photorefractive articles involve annealing the photorefractive materials at a temperature higher than the temperature range in which degradation occurs. The methods are particularly applicable to amorphous photorefractive materials and devices in which phase separation results in performance degradation or device failure.
