20100094012 | Heterodiamondoids - This invention is related to heteroatom containing diamondoids (i.e., “heterodiamondoids”) which are compounds having a diamondoid nucleus in which one or more of the diamondoid nucleus carbons has been substitutionally replaced with a noncarbon atom. These heteroatom substituents impart desirable properties to the diamondoid. In addition, the heterodiamondoids are functionalized affording compounds carrying one or more functional groups covalently pendant therefrom. This invention is further related to polymerizable functionalized heterodiamondoids. In a preferred aspect of this invention the diamondoid nuclei are triamantane and higher diamondoid nuclei. In another preferred aspect, the heteroatoms are selected to give rise to diamondoid materials which can serve as n- and p-type materials in electronic devices can serve as optically active materials. | 04-15-2010 |

20150376817 | OXYGEN AND NITROGEN CO-DOPED POLYACRYLONITRILE-BASED CARBON FIBER AND PREPARATION METHOD THEREOF - The invention relates to an oxygen and nitrogen co-doped polyacrylonitrile-based carbon fiber and a preparation method thereof. The oxygen and nitrogen co-doped polyacrylonitrile-based carbon fiber is prepared by electrochemical modification of a raw-material polyacrylonitrile-based carbon fiber, such that the surface thereof has an active layer formed by oxygen-containing active functional groups and nitrogen-containing active functional groups, wherein the nitrogen-containing active functional groups are obtained by activation of the doped nitrogen inherently contained in the raw-material polyacrylonitrile-based carbon fiber by means of electrochemical modification. The method for preparing the oxygen and nitrogen co-doped polyacrylonitrile-based carbon fiber comprises the following steps: placing the raw-material polyacrylonitrile-based carbon fiber in an electrolyte solution, subjecting it to cyclic treatment between electrochemical oxidation and electrochemical reduction, and thus obtaining the oxygen and nitrogen co-doped polyacrylonitrile-based carbon fiber. The oxygen and nitrogen co-doped polyacrylonitrile-based carbon fiber of the present invention has both the pseudo-capacitive properties for oxidation-reduction reactions and electrocatalytic properties for the cathodic oxygen reduction reaction. | 12-31-2015 |

20090030206 | METHOD FOR PRODUCING QUATERRYLENE-3,4:13, 14-TETRACARBOXY DIIMIDES BY DIRECT SYNTHESIS - A process for preparing quaterrylene-3,4:13,14-tetracarboximides of the general formula I | 01-29-2009 |
20090088572 | METHOD FOR PREPARING LADDERANES - Ditopic molecules in the form of linear reaction templates have been used to construct ladder-like hydrocarbons known as [n]-ladderanes (n=3,5). The templates assemble and position reactant molecules in the solid state by way of hydrogen bonds for [2+2] photodimerization. The products, which are based on recently identified naturally occurring frameworks, form stereospecifically, in gram quantities, and in quantitative yield. The control of reactivity achieved using linear templates provides a basis for the development of molecular tools, termed assemblers, that could be used to manufacture, with atomic-level precision, a wide range of products (e.g. molecular nanostructures) with unique properties. | 04-02-2009 |

The methods provide anisotropic solids without the need for rolling, rubbing, or stretching to impart orientational alignment of the molecules of the solid. The methods employ organic or organometallic compounds which are soluble orienting molecules. The solvent or solvent system must be sufficiently volatile to be removed without disruption of the molecular orientation. The soluble orienting molecules include those containing one or more hydrophilic and/or ionic groups and the solvent or solvent system can be a polar organic solvent or solvent system or an aqueous solvent or solvent system. The invention also provides novel compounds having quaterrylene, perylene and naphthalene ring systems carrying one or more hydrophilic and/or ionic groups. These novel compounds can exhibit useful absorption and fluorescence properties in solution and in the solid phase and can exhibit useful liquid crystalline properties. | 10-20-2011 |
