In the high-stakes world of advanced materials for organic electronics, particularly for OLEDs, the purity of constituent components can be the deciding factor between a successful, high-performance device and one that falters. N,N'-Diphenyl-N,N'-di-p-tolyl-Benzidine (CAS: 20441-06-9), a crucial hole transport material, exemplifies this principle. At NINGBO INNO PHARMCHEM CO.,LTD., we place an unwavering emphasis on the purity of our chemicals, understanding their profound impact on OLED device performance and longevity.

The function of N,N'-Diphenyl-N,N'-di-p-tolyl-Benzidine as a hole transport material (HTM) demands a highly ordered electronic structure and minimal impurities. Even trace amounts of contaminants can disrupt the smooth flow of charge carriers (holes) from the anode to the emissive layer. These impurities can:

  • Act as traps for holes, reducing their mobility and thus the overall efficiency of the device.
  • Introduce unwanted luminescence or quenching sites, affecting the color purity and brightness.
  • Accelerate the degradation of the organic layers, significantly shortening the operational lifespan of the OLED.
Therefore, materials like N,N'-Diphenyl-N,N'-di-p-tolyl-Benzidine, typically supplied as a white solid with a melting point around 165-169°C, must meet exacting purity standards, often specified at 97% or higher by analytical techniques such as Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC).

As a dedicated manufacturer and supplier based in China, NINGBO INNO PHARMCHEM CO.,LTD. is committed to delivering N,N'-Diphenyl-N,N'-di-p-tolyl-Benzidine that meets these stringent requirements.
