METAL COMPLEXES OF TETRA-(2,3-PYRIDONO-6)-PORPHYRAZINE Russian patent published in 2004 - IPC

Abstract RU 2242488 C1

FIELD: metalloorganic chemistry.

SUBSTANCE: invention relates to new derivatives of metalloporphyrazines that can be used as pigments, catalysts and materials used for making sensitive elements of gases. Invention describes metal complexes of tetra-(2,3-pyridono-6)-porphyrazine of the general formula (I):

wherein M means Cu, Co, Ni. Invention provides expanding the chromatic gamma of blue color pigments eliciting weak solubility in dimethylformamide, diluted mineral acids, insolubility in water and alkali aqueous solutions.

EFFECT: valuable chemical and physical properties of complexes.
