Description

3,4,9,10-Perylenetetracarboxylic Acid, Potassium Salt (1:4) is a highly functionalized perylene derivative, serving as a critical intermediate and functional material. Its value lies in its unique electronic and optical properties derived from the extended perylene core, which is essential for advanced material synthesis. This compound is primarily needed by manufacturers in the organic electronics, specialty pigments, and high-performance materials sectors for developing next-generation products.

Application

• Organic Semiconductor Precursor: A key building block for n-type organic semiconductors and electron-transport materials used in OLEDs, OFETs, and organic photovoltaics.
• Pigment and Dye Intermediate: Synthesis of high-performance perylene-based pigments (Perylene Reds, Violets) and vat dyes known for exceptional lightfastness and chemical stability.
• Functional Material Synthesis: Production of perylene diimide (PDI) derivatives for use in sensors, light-harvesting arrays, and supramolecular chemistry.
• Research & Development: Utilized in academic and industrial R&D for exploring novel conductive polymers, photoconductive materials, and fluorescent tags.
• Electrochromic Devices: A component in the development of materials for smart windows and displays due to its redox-active properties.
