For professionals in the organic electronics sector, the consistent availability of high-purity chemical intermediates is non-negotiable. One such critical material is 1,3,5-Tris(1-phenyl-1H-benzimidazol-2-yl)benzene, identified by CAS number 192198-85-9, and widely known in the industry as TPBi. This compound plays a vital role in enhancing the performance and longevity of electronic devices such as OLEDs and PLEDs, primarily functioning as an excellent electron transport layer (ETL) and exciton blocking layer (EBL).

Procurement managers and R&D scientists constantly seek reliable sources for these advanced materials. When you need to buy TPBi, understanding its specifications is the first step. Typically, TPBi is supplied as a white to off-white powder with a purity of 98% or higher, verified by HPLC. Its molecular formula is C45H30N6, with a molecular weight of 654.76 g/mol. Its melting point, usually in the range of 252-256°C, is a key indicator of its thermal stability, a crucial parameter for device fabrication and operational reliability. For companies looking to purchase this material, identifying a manufacturer that provides detailed specifications, including CAS 192198-85-9, and certificates of analysis (CoA) is paramount.

The application spectrum of TPBi is primarily within organic and printed electronics. In OLEDs, it optimizes the journey of electrons, ensuring they efficiently reach the emissive layer to combine with holes, thereby producing light. Its secondary function as an exciton blocker is equally important, as it helps confine energy within the emissive layer, increasing device efficiency and preventing degradation. Researchers developing new organic photovoltaic cells or other optoelectronic devices may also find TPBi to be a valuable component in their experimental setups. If you are a scientist or engineer aiming to buy this specialized chemical, it is beneficial to know that many suppliers offer it in various quantities, from grams for laboratory use to kilograms for pilot production.

When sourcing TPBi, especially in China, it's wise to consider suppliers that offer robust supply chain management and competitive pricing. Many manufacturers in China specialize in high-purity fine chemicals and OLED intermediates, providing consistent quality and timely delivery. As a buyer, you should always inquire about bulk order discounts and lead times. Establishing a relationship with a dependable manufacturer or distributor of TPBi can significantly streamline your procurement process and contribute to the success of your electronic product development.
