Boron subphthalocyanine compounds and method of making
View Patent ↗A compound comprising 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. The plurality of solubilizing substituents comprise 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, the hydrocarbyl group optionally containing one or more heteroatoms. The 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, the cyclic group being bonded to the boron atom by an oxygen containing linking moiety, the cyclic group optionally being 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.
