The performance of an Organic Light-Emitting Diode (OLED) is a delicate interplay of various organic layers, each engineered for a specific function. Among these, the Hole Transport Layer (HTL) is critical for facilitating the efficient movement of holes from the anode to the emissive layer. N,N'-Diphenyl-N,N'-di-p-tolyl-Benzidine (CAS: 20441-06-9) has emerged as a key material in this role, significantly contributing to the advancements seen in modern OLED displays and lighting. As a leading manufacturer and supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. is proud to provide this high-performance material to the global market.

The primary function of N,N'-Diphenyl-N,N'-di-p-tolyl-Benzidine in an OLED device is to act as an efficient hole transporter. Its molecular structure, characterized by conjugated aromatic rings and nitrogen atoms, allows for facile oxidation and stable radical cation formation, which are essential for effective hole mobility. When integrated as the HTL, it ensures that holes are efficiently injected from the anode and transported with minimal energy loss to the emissive layer. This efficiency directly translates to improved operational parameters for the OLED, including higher luminous efficacy, lower operating voltage, and extended device lifetime. The material typically appears as a white solid and possesses a melting point in the range of 165-169°C, indicating its robust thermal stability.
