BORON SUBPHTHALOCYANINE COMPOUNDS AND METHOD OF MAKING Russian patent published in 2018 - IPC C09B47/30 

FIELD: biochemistry.

SUBSTANCE: invention relates to boron subphthalocyanine compounds, which is a purple dye, and methods for making such compounds. Compound comprises a boron subphthalocyanine moiety, a plurality of solubilizing substituents positioned on peripheral cyclic groups of the boron subphthalocyanine moiety, and an axial substituent positioned on the boron atom. Plurality of solubilizing substituents comprises an oxygen or sulfur containing functional group and a substituted or unsubstituted, linear, branched or cyclic, aliphatic or aromatic terminal hydrocarbyl group that is 8 or more carbon atoms in length, wherein the hydrocarbyl group optionally contains one or more heteroatoms. Axial substituent is a cyclic group selected from the group consisting of heterocyclic amine groups, diaryl ketone groups, benzotriazole groups, benzyl alcohol groups and polycyclic aromatic hydrocarbon groups, wherein the cyclic group is bonded to the boron atom by an oxygen containing linking moiety, and the cyclic group is optionally substituted with one or more additional substituents. If the axial group is a benzyl alcohol group, the alcohol substituent of the benzyl alcohol is not the oxygen containing linking moiety.

EFFECT: technical result is improved physico-mechanical properties of dyes obtained from said compounds.
