Webirradiation in solvent-free conditions gave carbazole derivatives after elimination of the nitro group and in situ aromatization. While 3-nitro-1-(p-toluenesulfonyl)pyrrole 11 afforded indole derivatives, 4-nitro-1-(p-toluenesulfonyl)pyrazole 13 with cyclohexadiene 2 did not afford the expected cycloadduct but instead gave 1-cyclohexen-2-ylpyrazole 16. WebThe following tables list one or more solvents for common polymers. Polymer solubility is complex, though a few general rules apply, such as polar solvents work best with polar …
WebMultilayered structures improve the function of organic optoelectronic devices. For example, operational voltages can be substantially decreased, and the light output to current ratio increased, upon insertion of electron-injection/transport layers (ETLs) or hole-injection/transport layers at the cathode and anode interfaces, respectively. These layers … WebWhen solubility of the polymer in a given solvent is low, then it decreases exponentially with the molecular weight. Hence the larger polymers would have a exp(10) times lower …
WebThe method includes: obtaining a mixed solution containing oltipraz and a water-soluble polymer or a water-insoluble polymer in a solvent, the solvent being an organic solvent or purified water; and solid-dispersing the oltipraz in the polymer. WebDisclosed is a new ionic liquid monomer salt and methods of is synthesis and polymerization. The ionic liquid monomer salt is prepared by mixing equimolar amounts of an amine, such as tris[2-(2-methoxyethoxy)-ethyl]amine and an acid functionalized polymerizable monomer, such as 2-acrylamido-2-methyl-1-propanesulfonic acid, which is …
