In the specialized field of organic electronics, the precise molecular architecture and resulting properties of chemical compounds dictate their suitability for advanced device applications. 1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene, commonly abbreviated as TPBi and identified by CAS number 192198-85-9, is a prime example of such a material, extensively utilized in OLEDs and other photoelectric devices. Understanding its core properties is essential for any procurement manager or R&D scientist looking to integrate it into their next-generation products.

TPBi is characterized by its chemical structure, which features three 1-phenyl-1H-benzimidazol-2-yl groups attached to a central benzene ring. This specific arrangement imparts several advantageous properties. Physically, it typically appears as a white to almost white powder or crystal. Its molecular formula is C45H30N6, giving it a molecular weight of 654.76 g/mol. A critical physical property for many electronic applications is its melting point, which for TPBi generally falls within the range of 252-256°C. This relatively high melting point indicates good thermal stability, which is important for device longevity and the fabrication processes used in creating OLED panels.

From a functional perspective, TPBi is highly valued for its role as an electron transport material (ETM) and an exciton blocking layer (EBL). Its electron mobility is significant, allowing for efficient charge transfer within the electronic device architecture. This efficiency directly contributes to the improved performance of OLEDs and PLEDs, leading to higher brightness and power efficiency. When purchasing TPBi, specifications often highlight its purity, typically stated as 98% or 99% by HPLC. This high purity is crucial to minimize defects and ensure optimal device operation. For bulk purchases, it's important to buy from manufacturers in China who can consistently deliver this level of purity.

The density of TPBi is approximately 1.26 g/cm³. While solubility information can vary depending on the solvent, its primary applications are in solid-state electronic devices.
