For procurement professionals and R&D teams in the electronics and display industries, sourcing high-quality materials is paramount to the success of cutting-edge products like Organic Light-Emitting Diodes (OLEDs). One such critical material is 4,4'-Bis(2,2-diphenylvinyl)-1,1'-biphenyl (CAS: 142289-08-5), widely known as DPVBi. This organic semiconductor is indispensable for achieving the desired performance characteristics in modern OLEDs, particularly its role as a blue host-emitting material and its contribution to efficient charge transport.

As a dedicated manufacturer and supplier based in China, we understand the rigorous demands of the OLED market. The purity of DPVBi directly impacts the efficiency, color purity, and operational lifetime of OLED devices. Impurities, even in trace amounts, can act as charge traps or quenching sites, severely degrading performance. Therefore, sourcing DPVBi that has undergone rigorous purification processes, such as sublimation, is crucial. Our commitment is to provide materials with purity levels often exceeding 99.0% (HPLC or GC), ensuring that your devices meet and exceed performance expectations.

DPVBi's molecular structure (C₄₀H₃₀) endows it with a wide band gap and favorable electronic properties. Its functionality extends beyond being just a host material; it is also highly effective in Hole Injection Layers (HIL) and Hole Transport Layers (HTL). In these roles, DPVBi facilitates a smoother and more efficient transfer of holes from the anode to the emissive layer. This optimized charge injection and transport capability is vital for reducing driving voltage, increasing current efficiency, and ultimately, extending the lifespan of the OLED device.

When considering a supplier for DPVBi, it’s important to evaluate their technical expertise, quality control measures, and supply chain reliability. As a China-based manufacturer, we offer a distinct advantage by providing cost-effective solutions without compromising on quality. Our extensive experience in synthesizing and purifying organic electronic materials means we can consistently deliver DPVBi that meets the precise specifications required by advanced OLED manufacturing processes. For product formulators and engineers, understanding the material's physical properties, such as its yellow powder/crystal appearance and melting point of 207°C, is also key.

For purchasing managers looking to buy DPVBi, we offer a straightforward inquiry process. Simply reach out to our sales team for a competitive quote. We are dedicated to supporting your projects by providing not just the material, but also the technical information and consistent quality that you can rely on.
