Product Description:

Tetrachloroperylene dianhydride is an important organic pigment and dye intermediate. It is a derivative of perylene dianhydride, where four chlorine atoms are substituted on the perylene core. This chlorination significantly alters its electronic properties, including absorption/emission spectra and electron affinity, making it a key precursor for high-performance pigments and functional materials. Its primary application is in the synthesis of perylene-based pigments, known as perylene tetracarboxylic diimide (PTCDI) derivatives. These pigments exhibit exceptional chemical stability, thermal resistance, and vivid red to maroon colors, making them highly valuable for automotive coatings, industrial paints, plastics, and high-grade printing inks. Furthermore, due to its strong electron-accepting character and planarity, it serves as a crucial building block for n-type organic semiconductors used in organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs). The compound is typically synthesized through the chlorination of perylene dianhydride. As a fine chemical intermediate, it requires careful handling due to potential irritant properties and should be used in controlled environments. Its development underscores the role of functionalized polycyclic aromatic hydrocarbons in advancing materials for both traditional coloration and modern optoelectronic technologies.
