  • GRAPHENE NANORIBBONS, METHODS OF MAKING SAME, AND USES THEREOF
    Publication number: 20140212668
    Abstract: Provided are graphene nanoribbons (GNRs), methods of making GNRs, and uses of the GNRs. The methods can provide control over GNR parameters such as, for example, length, width, and edge composition (e.g., edge functional groups). The methods are based on a metal catalyzed cycloaddition reaction at the carbon-carbon triple bonds of a poly(phenylene ethynylene) polymer. The GNRs can be used in devices such a microelectronic devices.

  • Covalent Organic Frameworks and Methods of Making Same
    Publication number: 20140148596
    Abstract: Crystalline COFs comprising a phthalocyanine moiety and a boron-containing multifunctional linking group joined by boronate ester bonds. A method for making crystalline COFs comprising Lewis acid catalyzed formation of boronate ester bonds between protected catechol subunits and multifunctional linkers comprising boronic acid groups. The COFs can be used in applications such as, for example, electronic devices.

  • COVALENT ORGANIC FRAMEWORK FILMS, AND METHODS OF MAKING AND USES OF SAME
    Publication number: 20140037944
    Abstract: Multilayer structures comprising a covalent organic framework (COF) film in contact with a polyaromatic carbon (PAC) film. The multilayer structures can be made by combining precursor compounds in the presence of a PAC film. The PAC film can be for example, a single layer graphene film. The multilayer structures can be used in a variety of applications such as solar cells, flexible displays, lighting devices, RFID tags, sensors, photoreceptors, batteries, capacitors, gas-storage devices, and gas-separation devices.
