The extensive delocalization of the π-electrons affords the molecule useful properties, lending itself to applications in dyes and pigments. It is a highly complex organic synthesis. The search for the “perfect blue” plagued artists throughout history as they looked for a shade that captured hues visible – but not available – in nature, like the color of the ocean. 1960s. Such complexes are formally derivatives of Pc2−, the conjugate base of H2Pc. 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, the resulting paste being used thus directly in the preparation of lakes by adsorption on aluminum hydrate, or dried for incorporation into non-aqueous mediums. Both porphyrins and phthalocyanines function as planar tetradentate dianionic ligands that bind metals through four inwardly projecting nitrogen centers. Phthalo blue is a pigment you’ve seen thousands of times before, but maybe not had a name to put to the color – it’s the sea, the sky, and in the case of Bob Ross, snowy accents in paintings.

H2Pc and CuPc dissolve easily in sulfuric acid due to the protonation of the nitrogen atoms bridging the pyrrole rings. There are many derivatives of the parent phthalocyanine, where either carbon atoms of the macrocycle are exchanged for nitrogen atoms or the peripheral hydrogen atoms are substituted by functional groups like halogens, hydroxyl, amine, alkyl, aryl, thiol, alkoxy and nitrosyl groups. These modifications allow for the tuning of the electrochemical properties of the molecule such as absorption and emission wavelengths and conductance. Phthalocyanines are structurally related to other tetrapyrrole macrocyles including porphyrins and porphyrazines.
