20130292658 | ELECTRONIC DEVICES EMPLOYING ALIGNED ORGANIC POLYMERS - The devices can be fabricated by a method that permits active polymer chains to be polymerized on the surface of an electrode such that the active polymer chains are aligned with one another. The active polymer chains can also be covalently linked to a second electrode so the active polymer chains are located in an active layer of the device. The polymerization method can be paused and resumed at any point in the polymerization so nanoparticles can be added into the active layer. Additionally, the polymerization method allows that active polymer chains to be polymerized so they include junctions such as p-n junctions and Schottky junctions. | 11-07-2013 |
20130324666 | RAPID SELF-ASSEMBLY OF BLOCK COPOLYMERS TO PHOTONIC CRYSTALS - The invention provides a class of copolymers having useful properties, including brush block copolymers, wedge-type block copolymers and hybrid wedge and polymer block copolymers. In an embodiment, for example, block copolymers of the invention incorporate chemically different blocks comprising polymer size chain groups and/or wedge groups that significantly inhibit chain entanglement, thereby enhancing molecular self-assembly processes for generating a range of supramolecular structures, such as periodic nanostructures and microstructures. The present invention also provides useful methods of making and using copolymers, including block copolymers. | 12-05-2013 |
20130327392 | Chemically Linked Colloidal Crystals and Methods Related Thereto - Nanoparticles may be formed into colloidal crystals that are chemically linked to a substrate. In certain implementations, the nanoparticles are formed into a colloidal crystal on an initial substrate, and then brought into contact with a binding precursor capable of chemically linking the colloidal crystal to a final substrate. Reacting the binding precursor to chemically link the colloidal crystal to the final substrate chemically links the colloidal crystal to the final substrate via functional groups linked to the nanoparticles and the final substrate respectively. | 12-12-2013 |
