In the specialized field of OLED manufacturing, precise material specifications are not just guidelines; they are critical determinants of device performance, efficiency, and lifespan. For procurement managers and R&D scientists, understanding the exact properties of each chemical component is essential. This article delves into the specifics of 2,7-Dipentylbenzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone, identified by its CAS number 173409-41-1, a crucial material for advanced OLED applications.

What is CAS 173409-41-1?

CAS 173409-41-1 refers to 2,7-Dipentylbenzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraone. This complex organic molecule, often abbreviated as NTDA-C5H11, is a high-value chemical intermediate. Its molecular formula is C24H26N2O4, with a molecular weight of 406.47 g/mol. It is supplied as a solid, indicating its stability and ease of handling in laboratory and industrial settings. The minimum purity level typically specified for this compound is 97%, a critical factor for its intended applications.

Why is High Purity Essential for OLEDs?

OLED technology relies on the precise layering of organic materials, each performing a specific function—from charge injection and transport to light emission. Even minuscule amounts of impurities in these organic layers can significantly disrupt these processes. For NTDA-C5H11, its role in OLEDs is often related to charge transport or as a component within the emissive layers, where its high purity ensures:

• Enhanced Charge Mobility: A pure material allows electrons and holes to move freely, leading to more efficient charge recombination and higher luminous output.
• Improved Device Lifespan: Impurities can act as charge traps or defect sites, leading to device degradation and reduced operational lifetime. High-purity materials minimize these issues.
• Color Purity: The precise electronic structure of pure NTDA-C5H11 contributes to the desired emission spectrum, ensuring vibrant and accurate colors in displays.
• Consistent Performance: Sourcing from a reliable manufacturer that guarantees high purity ensures batch-to-batch consistency, vital for mass production.

Procurement Considerations for B2B Purchasers

When looking to buy CAS 173409-41-1, B2B purchasers should focus on several key aspects:

• Verified Purity: Always seek suppliers who clearly state the minimum purity level (e.g., 97%) and can provide documentation.
