Key Advantages of DPEPO for OLED Applications

Exceptional Thermal and Morphological Stability

DPEPO's unique structure, featuring steric ortho-substituted diphenylphosphine oxide (DPPO) groups, provides excellent thermal and morphological stability, crucial for device endurance and performance consistency. This makes it an ideal choice for OLED manufacturers seeking durable components.

Versatile Layer Functionality

Beyond its role as a host material, DPEPO effectively serves as an electron-transport layer (ETL) and a hole-blocking layer (HBL) in OLED devices. This multi-functionality simplifies device architecture and optimizes charge carrier management for improved efficiency.

Optimized for Blue TADF Emitters

The compound's properties are particularly well-suited for hosting blue TADF emitters, a notoriously challenging area in OLED technology. Its large band-gap and deep HOMO energy level contribute to the high efficiency and stable color purity required for next-generation displays.

Broad Application Spectrum of DPEPO

TADF OLED Host Material

As a primary host for blue TADF emitters, DPEPO is essential for creating high-performance OLED panels used in smartphones, televisions, and lighting. Consider purchasing DPEPO for your advanced display development.

Electron Transport Layer (ETL)

Its electron-transporting properties allow DPEPO to facilitate efficient electron injection and movement within the OLED stack, contributing to overall device efficiency.

Hole Blocking Layer (HBL)

DPEPO effectively blocks holes, preventing them from reaching the cathode and recombining non-radiatively, thus enhancing the efficiency of light emission.
