The relentless pursuit of more efficient and durable Organic Light-Emitting Diodes (OLEDs) has driven innovation in material science. A critical component in optimizing OLED performance is the strategic implementation of charge-blocking layers, specifically hole-blocking layers (HBLs). Among the advanced materials utilized for this purpose, 4,7-Diphenyl-1,10-phenanthroline (CAS 1662-01-7) has emerged as a highly effective and sought-after compound. As a specialized manufacturer and supplier of electronic chemicals, we are at the forefront of providing these cutting-edge materials.

OLED technology relies on the precise recombination of electrons and holes within an emissive layer to produce light. However, the uncontrolled diffusion of charge carriers can lead to inefficiencies and reduced device lifespan. Hole-blocking layers, such as 4,7-Diphenyl-1,10-phenanthroline, are strategically placed to confine holes within the emissive layer, preventing them from migrating to the electron transport layer. This confinement enhances the probability of electron-hole recombination in the desired zone, leading to brighter and more stable light emission.

The efficacy of 4,7-Diphenyl-1,10-phenanthroline as an HBL stems from its inherent electronic properties. It possesses a wide energy gap and a high ionization potential, characteristics essential for effectively blocking holes. Furthermore, its molecular structure imparts excellent electron mobility (approximately 5 × 10⁻⁴ cm²/Vs), which is significantly higher than many commonly used electron transport materials like Alq₃. This superior electron mobility not only aids in its function as an HBL but also contributes to efficient electron injection and transport within the OLED stack, especially when used in conjunction with lithium doping (BPhen:Li).
