Description

Perylene CAS NO 198-55-0 is a high-purity polycyclic aromatic hydrocarbon (PAH) characterized by its planar, fused-ring structure. This compound serves as a critical organic semiconductor and fluorescent dye intermediate, valued for its exceptional photostability and electron-transport properties. It is essential for manufacturers and R&D facilities in the organic electronics, specialty pigments, and advanced materials sectors seeking reliable, high-performance raw materials.

Application

• Organic Light-Emitting Diodes (OLEDs): Used as a core material in electron transport layers (ETLs) and host materials for red emitters due to its high electron affinity and thermal stability.
• Laser Dyes & Fluorescent Probes: Acts as a key precursor for synthesizing perylene diimides (PDIs), which are vital for high-performance laser dyes, biological staining, and sensor applications.
• Pigments and Dyes: Serves as a starting material for manufacturing high-grade perylene-based pigments (e.g., Pigment Red 179, Pigment Violet 29) known for outstanding weatherfastness and color strength.
• Organic Photovoltaics (OPVs): Employed in the development of non-fullerene acceptors and active layers in solar cells to improve light absorption and charge carrier mobility.
• Chemical Research & Synthesis: A fundamental building block in organic chemistry for constructing larger π-conjugated systems and supramolecular structures.
• Electrophotography & Xerography: Utilized in the charge generation layers of photocopiers and laser printers.
