Phthalocyanine green G, which has many commercial names, is a synthetic green pigment from the group of phthalocyanine dyes, a complex of copper(II) with chlorinated phthalocyanine. It is a soft green powder, which is insoluble in water. [1] It is a bright, high intensity colour used in oil and acrylic based artist's paints, and in other ...
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.
Chemical structure of Phthalocyanine Green G, a major green organic pigment. The dominant green pigment is Phthalocyanine Green G, which is sold under many commercial names. 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 ...
The Monstral blue found to coat the inside of copper vessels used to process phthalic acid derivatives had led to the discovery of Phthalocyanine in 1907. Attracted by the brilliance, stability and insolubility of this chromophore, attempts were made to reversibly modify it so that it would be carried into fabric in a solution and then easily precipitated (ingrained) into an unleachable but ...
This pigment absorbs red and green light, but reflects blue—giving the substance a blue-colored appearance. Like all materials, the color of pigments arises because they absorb only certain wavelengths of visible light. The bonding properties of the material determine the wavelength and efficiency of light absorption. [5]
The infrared absorption spectrum of NASA laboratory sulfur dioxide ice is compared with the infrared absorption spectra of ices on Jupiter's moon, Io credit NASA, Bernard Schmitt, and UKIRT. Absorption spectroscopy is useful in chemical analysis [5] because of its specificity and its quantitative nature. The specificity of absorption spectra ...
Copper phthalocyanine (CuPc), also called phthalocyanine blue, phthalo blue and many other names, is a bright, crystalline, synthetic blue pigment from the group of dyes based on phthalocyanines. Its brilliant blue is frequently used in paints and dyes .
A colorimeter is a device used to test the concentration of a solution by measuring its absorbance of a specific wavelength of light. To use this device, different solutions must be made, and a control (usually a mixture of distilled water and another solution) is first filled into a cuvette and placed inside a colorimeter to calibrate the machine.
