Abstract
Official abstract text for this publication.
A method of producing a hydrazine-coordinated Cu chalcogenide complex, including: a step (I) in which Cu or Cu 2 Se and a chalcogen are reacted in dimethylsulfoxide in the presence of hydrazine, a step (II) in which a solution obtained in the step (I) is subjected to concentration and filtration, and a step (III) in which a purifying solvent is added to a solution obtained in the step (II).
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing and purifying a hydrazine-coordinated Cu chalcogenide complex free of an amine solvent, the method comprising: a step (I) in which Cu or Cu 2 Se and a chalcogen are reacted in dimethylsulfoxide in the presence of hydrazine and free of an amine solvent, thereby forming a solution of a hydrazine-coordinated Cu chalcogenide complex; a step (II) in which hydrazine is removed from the solution obtained in the step (I) under reduced pressur…
