Solid electrolytic capacitor containing a conductive polymer
ActiveUS20080232037A1Hybrid capacitor electrolytesSolid electrolytic capacitorsOligomerConductive polymer
A method for forming an electrolytic capacitor is disclosed. The method includes forming a conductive polymer coating by polymerizing a monomer in the presence of less than a stoichiometric amount of an oxidative polymerization catalyst. The present inventor has found that the use of less than the stoichiometric amount of the oxidative polymerization catalyst per mole of monomer can slow the polymerization of the monomer, creating oligomers that are shorter in length than if fully polymerized into a polymer. Without wishing to be bound by theory, it is believed that these shorter oligomers provide better penetration into the porous anode. Thus, the resulting conductive polymer layer can be more intimately positioned with respect to the anode. As a result, the formed capacitor can exhibit better performance.

Synthesis of macrocyclic tetraamido-N ligands
InactiveUS6011152AIncrease productionLow costOrganic compound preparationIron group organic compounds without C-metal linkagesArylCatalytic oxidation
New synthetic methods for the preparation of macrocyclic amido-N donor ligands are provided. The primary method of the present invention involves in general only two synthetic steps. In the first step, an alpha or beta amino carboxylic acid is allowed to react with an optimal (approximately stoichiometric) amount of an activated malonate or oxalate derivative with mild heating. Upon completion of the double coupling reaction, hydrolysis of the reaction mixture yields a diamide containing intermediate (a macro linker). In the second step, stoichiometric amounts of a diamine, preferably an orthophenylene diamine, are added to the macro linker intermediate in the presence of a coupling agent and heat. This second double coupling reaction, is allowed to proceed for a period of time sufficient to produce a macrocyclic tetraamido compound. The substituent groups on the alpha or beta amino carboxylic acid, the malonate, and the aryl diamine may all be selectively varied so that the resulting tetraamido macrocycle can be tailored to specific desired end uses. The macrocyclic tetraamide ligand may then be complexed with a metal, such as a transition metal, and preferably the middle and later transition metals, to form a robust chelate complex suitable for catalyzing oxidation reactions.
