The LD50 (rats, oral) is 10 g/kg.[12]. At the initial discovery of Pc, its uses were primarily limited to dyes and pigments. Opacity/transparency: Semi opaque. [10], Phthalocyanine is formed through the cyclotetramerization of various phthalic acid derivatives including phthalonitrile, diiminoisoindole, phthalic anhydride, and phthalimides. Phthalocyanine is also used on some recordable DVDs. Phthalocyanine definition is - a bright greenish-blue crystalline compound C32H18N8; also : any of several metal derivatives that are brilliant fast blue to green dyes or pigments. The excellent colouristic properties have earned them a place on the palette of many well-known painters such as Kandinsky, Yves Klein, Barnett Newman, Roy Lichtenstein, Jackson Pollock, etc. Phthalocyanines are structurally related to other tetrapyrrole macrocyles including porphyrins and porphyrazines. [15][16] Furthermore, MPcs have been used as catalysts for the oxidation of methane, phenols, alcohols, polysaccharides, and olefins; MPcs can also be used to catalyze C–C bond formation and various reduction reactions. [12] Using such methods, approximately 57,000 tonnes (63,000 tons) of various phthalocyanines were produced in 1985.[12]. SCROLL DOWN FOR REVIEWS . [17] Silicon and zinc phthalocyanines have been developed as photosensitizers for non-invasive cancer treatment. Colour index: 74100. History of the Colors Phthalo Blue and Ultramarine, Real and Synthetic. 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. Pigment Type. [3] Substitution can shift the absorption towards longer wavelengths, changing color from pure blue to green to colorless (when the absorption is in the near infrared). They remarked on the enormous stability of these complexes but did not further characterize them. Metal complexes derived from Pc2−, the conjugate base of H2Pc, are valuable in catalysis, organic solar cells, and photodynamic therapy. They remarked on the enormous stability of these complexes but did not further characterize them. [9] It was not until 1934 that Sir Patrick Linstead characterized the chemical and structural properties of iron phthalocyanine. Two copper phthalocyanines are shown in the figure below. In the last few years we have broken the bounds of existing manufacturing capabilities to emerge as leading manufacturer & exporter of Phthalocyanine Pigments and Food Colours from India. Chemical Formula. There has since been significant research on H2Pc and MPc resulting in a wide range of applications in areas including photovoltaics, photodynamic therapy, nanoparticle construction, and catalysis. 1960s. [11] Alternatively, heating phthalic anhydride in the presence of urea yields H2Pc. Colour index: 74160 . Shortened from phthalocyanine. Phthalocyanine and derived metal complexes (MPc) tend to aggregate and, thus, have low solubility in common solvents. Get your own music profile at Last.fm, the world’s largest social music platform.

In 1907, an unidentified blue compound, now known to be phthalocyanine, was reported. It is composed of four isoindole units linked by nitrogen atoms. More often, MPc is synthesized rather H2Pc due to the greater research interest in the former. Listen to music from Phthalo_blue’s library (322,671 tracks played).

However when photographed, this line of colors tends to turn brown in the camera lens, being logically attributed to the fact that though it absorbs all other colors of light, there must be some refractive or reflective bounce of the initial bronze tone of the mineral in crystal that is not evident to the eye.”. Does English Have More Words Than Any Other Language? Since, the color has continued to evolve, and its association with calming, natural elements like the sky and clear water have solidified it as a universal favorite among artists, interior designers and other disciplines. Both porphyrins and phthalocyanines function as planar tetradentate dianionic ligands that bind metals through four inwardly projecting nitrogen centers. History of Use Phthalocyanine pigments were developed around the 1930s and have been widely used in many areas besides artists’ pigments. 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. Serie: A. Pigment classification: PB 15: 2. Phthalo Blue PB15:3 is a structural variant of Phthalo Blue PB15 that produces more greenish tones. These modifications allow for the tuning of the electrochemical properties of the molecule such as absorption and emission wavelengths and conductance. History of the Colors Phthalo Blue and Ultramarine, Real and Synthetic Edgar Coudal It's a color conundrum: Can you use a different blue for a limited-palette project if phthalo blue isn't a color you already have? This allows you to work wet-in-wet at your own pace. H2Pc and CuPc dissolve easily in sulfuric acid due to the protonation of the nitrogen atoms bridging the pyrrole rings. [13] Modification of the substituents attached to the peripheral rings allows for the tuning of the absorption and emission properties of Pc to yield differently colored dyes and pigments. History.
