摘要:An ion exchange polymer has an ionomer structure containing poly(phenylene) compound integrated with functionalized poly(fluorene). The ion conducting co-polymer includes a poly(fluorene) compound and a poly(phenylene) compound covalently bonded together. The poly(fluorene) compound has a 9H-fluorene structure that is a polycyclic aromatic hydrocarbon having a center ring with five carbon atoms, and a benzene ring on each of opposing sides of said center ring. The poly(phenylene) compound is covalently bonded to each of the pair of benzene rings of the poly(fluorene) compound. A pair of sidechains extends from the center ring of the poly(fluorene) compound to a respective terminal group. The terminal groups are configured on sidechains of the poly(fluorene) compound and can be converted into functional groups such as quaternary ammonium or n-methyl piperidine functional groups. The ion exchange polymer may include a porous scaffold support.

标题 :Formation of 2D flakes from chemical cutting of prefabricated nanoparticles and van der Waals heterostructure devices made using the same

摘要:A method of synthesis of two-dimensional (2D) nanoflakes comprises the cutting of prefabricated nanoparticles. The method allows high control over the shape, size and composition of the 2D nanoflakes, and can be used to produce material with uniform properties in large quantities. Van der Waals heterostructure devices are prepared by fabricating nanoparticles, chemically cutting the nanoparticles to form nanoflakes, dispersing the nanoflakes in a solvent to form an ink, and depositing the ink to form a thin film.

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 :Aromatic tertiary amines, enamines, deoxybenzoins and benzils

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.
