Products Description

Phthalocyanine, also known as phthalocyanine, phthalocyanine, a class of dark compounds, similar in structure to the porphyrin ring (or porphyrin complex, porphyrin), is a dye composed of four pyrrole nuclei and has a porphyrin ring structure. According to molecular orbital theory, conjugated systems with this structure are very stable. Phthalocyanine was developed as a blue to green pigment with the highest fastness. Later, dyes with excellent performance were derived by various methods. There are metal phthalocyanines and non-metal phthalocyanines. There are two types of metal phthalocyanines: one contains copper, iron, zinc, cobalt, platinum, etc., and the atomic radius is close to the radius of the central gap of the phthalocyanine molecule. These metals are bonded to two of the four nitrogen atoms in atomic bonds, to the other two in valence bonds and these are called stable types; Another such as containing sodium, potassium, barium, cadmium, magnesium, lead, etc., the atomic radius of the metal atom is too long, can not form a coordination bond with the phthalocyanine, and can only be combined with two nitrogen atoms to form an atomic chain salt. The former is treated with concentrated sulfuric acid, and the metal is not removed; Slightly soluble in organic solvents; It can sublimate under high temperature vacuum. The latter, in case of acid or water, the metal is easily removed; Insoluble in organic solvents; It does not sublimate under high temperature vacuum. The four benzene rings in the phthalocyanine molecule are easy to be substituted and sulfonated. The dyes derived from phthalocyanines are direct dyes, sulfide dyes, VAT dyes, phthalocyanins, special water-soluble dyes and reactive dyes. Metal phthalocyanines are prepared by co-heating phthalic anhydride or phthalonitrile with metal or metal salts. The above information was edited by Tong Tong of Chemicalbook.
