What is phthalocyanine used for?
Phthalocyanines are the second most important class of colorant, and copper phthalocyanine is the single largest-volume colorant sold. Traditional uses of phthalocyanine colorants are as blue and green pigments for automotive paints and printing inks and as blue/cyan dyes for textiles and paper.
Where does phthalocyanine come from?
Phthalocyanine is formed through the cyclotetramerization of various phthalic acid derivatives including phthalonitrile, diiminoisoindole, phthalic anhydride, and phthalimides. Alternatively, heating phthalic anhydride in the presence of urea yields H 2Pc.
What are phthalocyanine dyes?
Chemical modifications of substituted groups, metal centers, and axial ligands on the porphyrinato metal complexes show various functionalities. Normal porphyrin complexes have sharp absorptions, the so-called Soret band, around 400-500 nm, and the Q band around 500-700 nm that is a relatively weak absorption.
What Colour is phthalocyanine?
Phthalocyanine is an intensely blue-green-colored aromatic macrocyclic compound that is widely used in dyeing and the first phthalocyanine (Pc) was synthesized accidentally in 1907 as an unidentified blue compound when o-cyanobenzamide was heated at high temperature and that substance is currently known to be the metal …
How is phthalocyanine blue made?
Phthalocyanine blue is prepared by heating a mixture of phthalic anhydride, urea, and copper chloride. It then becomes copper-phthalocyanine but is not conditioned as a pigment until it is dissolved in concentrated sulfuric acid and carefully washed in excess water and filtered.
Is phthalocyanine a coordination compound?
coordination compounds Phthalocyanine complexes (e.g., copper phthalocyanine), containing large-ring ligands closely related to the porphyrins, constitute an important class of dyes for fabrics.
