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.
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]
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.
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.
