Application
Pigment Blue 15, purified by sublimation, is a versatile dark blue fine crystalline powder primarily composed of Copper(II) phthalocyanine. This substance plays a significant role in photosensitizer chemistry, aiding in uniform polymerization, luminescence chemistry, and spectrophotometric analysis. It is employed in various industrial applications, including the production of enamels, linoleum, inks, plastics, and rubber goods. Additionally, Pigment Blue 15 finds use in advanced technologies such as rewritable CDs or DVD printing, organic solar cells, and display devices like OLEDs, OTFTs, wearable displays, and e-paper. Known for its utility in organic photovoltaics, it serves as an electron donor and demonstrates effective hole-injection capabilities in light-emitting diodes, enhancing device efficiency and stability. The pigment's specific properties include a reddish shade, high heat resistance, lightfastness, and excellent acid and alkali resistance, making it suitable for a wide range of applications. With its minimal light absorption in certain spectra and effective electron-blocking properties, Pigment Blue 15 is a critical component in emerging technologies and traditional manufacturing processes.
