| Description | Phthalocyanine is a macrocyclic compound, It consists of four isoindole-class [(C6H4)C2N] units linked by four nitrogenatoms to form a conjugated chain, which take play in hosting various different metal ions in its centre. This macrocyclicstructure like porphyrins(biopigments) is highly coloured Phthalocyanine derivatives derived from the basic compound of(C6H4C2N)4N4 are used as light-fast blue or green pigments. The hosted metals and substituted groups result in distinctcolors; phthalocyanine (blue-green), copper phthalocyanine (blue), chlorinated copper phthalocyanine (green), and sulfonatedcopper phthalocyanine (green). They have also been involved in the study of photosensitizer chemistry or metal complexchemistry such as transition-metal complex catalyst chemistry for uniform polymerization, luminescence chemistry andspectrophotometric analysis, organic synthesis and polymerization. Phthalocyanine pigments are used in enamels, linoleum,inks, plastics, and rubber goods. Photoisomerizable phthalocyanines are used in rewritable CD or DVD printing. Somephthalocyanines such as fluoraluminium phthalocyanine are used in cancer treatment. Due to pi-electron cloud overlaps,phthalocyanines exhibit semiconductor property. Organic semiconductors have some merits of self radiation, flexibility, lightweight, easy fabrication, and low cost. They have been investigated as organic electroluminescence materials for theapplications in organic solar cells, biosensitizers and display devices such as OLED(Organic Light Emitting Diode),OTFT(Organic Thin Film Transistor), Wearable Display, and e-paper. Phthalocyanine green is a bluish green pigment with outstanding lightfastness and stability commercially produced since 1938. Phthalocyanine blue is a bright blue pigment with outstanding properties which was in use by many modern painters such as Mondrian, Pollock, and others. |
| Organic pigment | Phthalein is an important organic pigment. Its chromatography is mainly blue and green. It is of bright color and strong coloring force. It features excellent weatherability, heat resistance, solvent resistance, acid resistance and alkali resistance. It is widely used in paints, ink, plastic coloring, pigment printing, synthetic fiber raw coloring etc.. It can also be used as catalyst, grease, electrophotographic sensitizer, solar cell and so on. Its main variety is copper phthalocyanine (phthalocyanine blue). Metal phthalocyanines are also used in a small amount. Copper phthalocyanine has a variety of crystal forms, usually taking the alpha and beta forms. The hydrogen atoms on the benzene ring are replaced by halogen, and the color changes from blue to green. Phthalein, also known as phthalocyanine, is a kind of dark compound. The structure is similar to porphyrin ring (or porphyrin complex, porphyrin). It is a dye consisting of four pyrrole nuclei with porphyrin ring structure. According to the molecular orbital theory, the conjugated system with this structure is very stable. Phthalocyanine is used as a blue to green pigment with the highest fastness. Afterwards, dyes with excellent properties are derived from various methods. It can be divided into metal phthalocyanine and non metal phthalocyanine. There are two types of metal phthalocyanines: the first type contains copper, iron, zinc, cobalt, platinum, etc. The radius of the atom is close to the radius of the center gap of the phthalocyanine molecule. These metals are bonded to two nitrogen atoms in four nitrogen atoms by atomic bonds, and the other two nitrogen atoms are bonded by valence bonds. The other type contains sodium, potassium, barium, cadmium, magnesium, lead and so on. The atomic radius of the metal atom is too long and cannot form the valence bond with phthalocyanine. It can only be combined with two nitrogen atoms by atomic chain into salt. The former is treated with concentrated sulfuric acid, and the metal is not removed. It is slightly soluble in organic solvents and can be sublimed under high temperature and vacuum. The latter, in the case of acid or water, is easy to remove. It is insoluble in organic solvents and does not sublimate under high temperature and vacuum. Four benzene rings in phthalocyanine molecules are more easily substituted and sulfonated. The dyes derived from phthalocyanines include direct dyes, sulphur dyes, vat dyes, phthalocyanine dye (phthalocyanines), special water-soluble dyes and reactive dyes. Metal phthalocyanines are prepared by co heating of phthalic anhydride or phthalonitrile with metal or metal salts. |

| Uses | Phthalocyanine is a common macrocylic blue-green dye able to form coordination complexes with many elements on the periodic table. |
| Definition | ChEBI: A tetrapyrrole fundamental parent that consists of four isoindole-type units, with the connecting carbon atoms in the macrocycle replaced by nitrogen. |
| Definition | phthalocyanine: A synthetic compoundhaving molecules with fourisoindole rings linked by –N= bridges.The structure is similar to that of theporphyrins. It can form complexeswith central metal ions. Copperphthalocyanines are used as dyes. |
| Flammability and Explosibility | Not classified |
| Agricultural Uses | Phthalocyanine is a group of benzoporphyrins whichhave strong pigmenting power, forming a family of dyes. The basic structure of the molecule comprises fourisoindole groups (C6H4,)C2N, joined by four nitrogenatoms. Four commercially important modifications are:(a) metal free phthalocyanine (C6H4C2N)4, having a bluegreencolor,(b copper phthalocyanine in which a copperatom is held by secondary valences of the isoindolenitrogen atoms, (c) chlorinated copper phthalocyanine,green, in which 15 to 16 hydrogen atoms are replaced bychlorine, and (d) sulphonated copper phthalocyanine,water-soluble and green, in which two hydrogens arereplaced by sulphonic acid groups. It is used in decorativeenamels and automotive finishes; chlorophyll andhaems have basic phthalocyanine structures in theirmolecules. |
| Purification Methods | Purify phthalocyanine by sublimation (two to three times) in an argon flow at 300-400Pa; and similarly for the Cu(II), Ni(II), Pb(II), VO(II) and Zn(II) phthalocyanine complexes. [Beilstein 26 III/IV 4255.] |
