The organic light-emitting diode (OLED) industry continues to push the boundaries of display and lighting technology. For procurement managers tasked with sourcing the essential materials for these advanced devices, a deep understanding of technical specifications is not just beneficial – it's critical. The performance, reliability, and longevity of any OLED product hinge on the quality and purity of its constituent organic compounds.

At the forefront of OLED material innovation are compounds like 5,5'-(1,3,8,10-tetraoxoanthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline-2,9(1H,3H,8H,10H)-diyl)diisophthalic Acid (CAS: 800381-20-8). This complex molecule, and others like it, are vital for creating efficient and stable OLED devices. As a leading manufacturer and supplier in China, we focus on providing materials that meet exacting industry standards. Here’s what procurement managers should look for:

1. Purity: The Undisputed Champion

This cannot be stressed enough. For OLED materials, purity is paramount. Even minute traces of contaminants can act as charge traps, quench luminescence, or catalyze degradation pathways. This leads to reduced brightness, color shifts, and a significantly shortened device lifespan. We guarantee a minimum purity of 97% for our diisophthalic acid derivative, ensuring it meets the high demands of OLED fabrication. Always inquire about the specific analytical methods used for purity verification (e.g., HPLC, GC-MS).

2. Chemical Structure and Molecular Weight

The precise chemical structure dictates the electronic and optical properties of the material. Understanding the molecular formula (MF) and molecular weight (MW) is essential for calculating doping concentrations, layer thicknesses, and material quantities for synthesis. The complex name of our diisophthalic acid derivative hints at its sophisticated structure, designed for specific functions within the OLED stack.

3. Physical Appearance and Form

Materials are typically supplied as solids (powders or crystals). This indicates the need for vacuum thermal evaporation or sublimation techniques for deposition in manufacturing. Understanding the physical form is also important for handling, storage, and safety protocols. Our 5,5'-(1,3,8,10-tetraoxoanthra[2,1,9-def:6,5,10-d'e'f']diisoquinoline-2,9(1H,3H,8H,10H)-diyl)diisophthalic Acid is supplied as a solid, suitable for standard deposition processes.

4. Applications and Functionality

Knowing the intended application – whether as an emissive material, charge transport layer, host material, or dopant – helps in selecting the right compound. Our diisophthalic acid derivative is versatile and utilized in OLEDs, OFETs, and OPVs, highlighting its broad utility in optoelectronics.

5. Storage Conditions and Stability

To maintain material integrity, proper storage is crucial. Our materials are recommended to be stored in a cool, dry place, with containers kept closed. This helps prevent degradation from moisture or air exposure.

Sourcing from China: A Strategic Advantage

As a manufacturer based in China, we offer a distinct advantage: access to high-quality materials like CAS 800381-20-8 at competitive prices, coupled with robust manufacturing capabilities. We encourage procurement managers to request a quote and sample to experience the quality and reliability we offer. Partnering with a trusted supplier is key to navigating the complexities of the OLED material market and ensuring the success of your innovations.
