    摘要: This invention relates to a chemical transformation of the bridging organic groups in metal oxide materials containing bridging organic groups, such as bridged organosilicas, wherein such a transformation greatly benefits properties for low dielectric constant (k) applications. A thermal treatment at specific temperatures is shown to cause a transformation of the organic groups from a bridging to a terminal configuration, which consumes polar hydroxyl groups. The transformation causes k to decrease, and the hydrophobicity to increase (through ‘self-hydrophobization’). As a result of the bridge-terminal transformation, porous organosilica films are shown to have k 6 GPa, do not require additional chemical surface treatment for dehydroxylation (hydrophobicity).

    摘要: This invention describes methods of synthesis and applications of planarized photonic crystals. Provided are simple, quick, reproducible and inexpensive methods that combine self-assembly and lithography to achieve the first examples of vectorial control of thickness, structure, area, topology, orientation and registry of colloidal crystals that have been patterned in substrates for use in lab-on-chip and photonic chip technologies. 1-, 2 and 3-D colloidal crystals patterned either on or within substrates can be used for templating inverted colloidal crystal replica patterns made of materials like silicon as well as building micron scale structural defects in such colloidal crystals. These photonic crystals can form the basis of a range of optical devices that may be integrated within photonic chips and coupled to optical fibers and/or waveguides to enable development of highly compact planarized optically integrated photonic crystal devices and circuits for use in future all-optical computers and optical telecommunication systems.

    摘要: A compressible photonic crystal comprising a polymer with an ordered array of voids, the photonic crystal having a reflectance in a first wavelength range for light incident to its incident surface and its opposing incident surface; wherein compression against at least a portion of at least one of the surfaces shifts the reflectance to a second wavelength range in at least that portion of that surface. The crystal may be used in authentication devices of various types.

    摘要: The present invention discloses a widely wavelength tunable polychrome colloidal photonic crystal device whose optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimension, effected by a predetermined change in the electronic configuration of the composite material. In its preferred embodiment, the material is a composite in the form of a film or a patterned film or shape of any dimension or array of shapes of any dimension comprised of an organized array of microspheres in a matrix of a cross-linked metallopolymer network with a continuously variable redox state of charge and fluid content. The chemo-mechanical and electro-mechanical optical response of the colloidal photonic crystal-metallopolymer gel is exceptionally fast and reversible, attaining its fully swollen state from the dry shrunken state and vice versa on a sub-second time-scale. These composite materials can be inverted by removal of the constituent microspheres from the aforementioned colloidal photonic crystal metallopolymer-gel network to create a macroporous metallopolymer-gel network inverse colloidal photonic crystal film or patterned film or shape of any dimension optical Bragg diffraction stop bands and higher energy bands wavelength, width and intensity can be redox tuned in a continuous and fine, rapid and reversible, reproducible and predictable fashion and over a broad spectral range by a controlled expansion or contraction of the colloidal photonic lattice dimensions.
