Copper phthalocyanine is a complex of copper(II) with the conjugate base of phthalocyanine, i.e. Cu 2+ Pc 2−. The description is analogous to that for copper porphyrins, which are also formally derived by double deprotonation of porphyrins. CuPc belongs to the D 4h point group. It is paramagnetic with one unpaired electron per molecule.
Chemical structure of copper phthalocyanine. Copper phthalocyanine ("phthalo blue") is a synthetic blue pigment frequently used in paints, inks, and dyes. It is highly valued for its superior properties such as light fastness, tinting strength, covering power and resistance to the effects of alkalis and acids. It has the appearance of a blue ...
Phthalocyanine green is derived from phthalocyanine blue by chlorination in the presence of aluminium trichloride. The stoichiometry for the complete chlorination is shown: [1] Cu(C 32 H 16 N 8) + 16 Cl 2 → Cu(C 32 N 8 Cl 16) + 16 HCl. In practice, this pigment is a mixture of isomers and degrees of chlorination.
Copper phthalocyanine; Aluminosilicate pigments. Ultramarine (PB29): a synthetic or naturally occurring sulfur containing silicate mineral - Na 8–10 Al 6 Si 6 O 24 S 2–4 (generalized formula) Persian blue: made by grinding up the mineral Lapis lazuli.
It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
It is a synthetic green pigment from the group of phthalocyanines, a complex of copper(II) with chlorinated phthalocyanine. It is a soft green powder, which is insoluble in water. [ 2 ] It is a bright, high intensity colour used in oil and acrylic based artist's paints , and in other applications.
Phthalocyanine (H 2 Pc) is a large, aromatic, macrocyclic, organic compound with the formula (C 8 H 4 N 2) 4 H 2 and is of theoretical or specialized interest in chemical dyes and photoelectricity. It is composed of four isoindole units [ a ] linked by a ring of nitrogen atoms.
Colorants (both dyes and pigments) are listed using a dual classification which use the Colour Index Generic Name (the prime identifier) and Colour Index Constitution Numbers. These numbers are prefixed with C.I. or CI, for example, C.I. Acid Orange 7 or C.I. 15510. (This abbreviation is sometimes mistakenly thought to be CL, due to the font ...
