标 题 :Fabrication of carbon nanotube films from alkyne-transition metal complexes

权利人:UNIV CALIFORNIA
摘要:A simple method for the production or synthesis of carbon nanotubes as free-standing films or nanotube mats by the thermal decomposition of transition metal complexed alkynes with aryl, alkyl, alkenyl, or alkynyl substituents. In particular, transition metal (e.g. Co, Ni, Fe, Mo) complexes of diarylacetylenes, e.g. diphenylacetylene, and solid mixtures of these complexes with suitable, additional carbon sources are heated in a vessel. More specifically, the heating of the transition metal complex is completed at a temperature between 400-800° C. and more particularly 550-700° C. for between 0.1 to 24 hours and more particularly 0.5-3 hours in a sealed vessel under a partial pressure of argon or helium.

摘要:Described herein are anionic phenylene oligomers and polymers, and devices including these materials. The oligomers and polymers can be prepared in a convenient and well-controlled manner, and can be used in cation exchange membranes. Also described is the controlled synthesis of anionic phenylene monomers and their use in synthesizing anionic oligomers and polymers, with precise control of the position and number of anionic groups.

标 题:Nanoparticle synthesis on substrates with removable coatings
发明人：MIRKIN CHAD; SMITH PETER
权利人:UNIV NORTHWESTERN
摘要:A method of forming nanoparticles on a substrate includes coating a substrate with a substrate coating, depositing a precursor ink comprising a polymer and one or more metal ions and/or one or more metal ion precursors onto the substrate coating to form a plurality of polymer nanoreactors comprising the one or more metal ions or the one or more metal ion precursors contained within the polymer nanoreactor, annealing the substrate having the polymer nanoreactors formed on the substrate coating to aggregate the one or more metal ions within the nanoreactor and form nanoparticles within the polymer nanoreactors; and removing the substrate coating thereby resulting in the nanoparticles formed on the substrate.

标题 :Aromatic tertiary amines, enamines, deoxybenzoins and benzils
发明人：HAY ALLAN S; PAVENTI MARTINO
权利人:HAY ALLAN S; PAVENTI MARTINO
摘要:A novel synthesis of aromatic tertiary amines involves reacting an aromatic anil and an aromatic ether in a molar ratio of 1:1; adjusting the ratio to 2:1 produces novel enamines and by employing a two step process for enamine production, various unsymmetrically substituted enamines can be obtained which are readily hydrolyzed to corresponding deoxybenzoins which in turn are readily oxidized to benzils, the aromatic tertiary amines may be used to produce charge transport layers in xerography, while the benzils may be used to produce a variety of desired polymers.
