BTB is mainly used as an electron transport material in organic light-emitting devices (OLEDs), and as phosphorescent host material for green and red light-emitting diodes.

Key Features of BTB

  • Electron Transport Layer (ETL) Material: Due to its unique chemical properties i.e. two triazine units, BTB serves as an excellent material in electron transport layers, ensuring OLEDs operate efficiently and have extended lifetimes.
  • Hole Blocking Layer (HBL) Material: BTB is also utilized as a hole blocking layer material, which is crucial for the balanced transportation of electrons and holes in OLED devices.
  • TADF Material: BTB plays a vital role in Thermally Activated Delayed Fluorescence (TADF) OLEDs, contributing to their high efficiency and longevity.
  • Host Material: In addition to its other roles, BTB is used as a host material in various OLED configurations, enhancing their overall performance. It can be used as a phosphorescent host material for red and green light-emitting diodes.

The Role of BTB in Modern OLEDs

In the current landscape of OLED technology, materials that offer high efficiency, durability, and low energy consumption are in high demand. BTB, with its multifaceted properties, is perfectly aligned with these requirements. Its role as an ETL and HBL material ensures that OLEDs not only function efficiently but also have a longer lifespan.
