Usage

Classification

Blue emitter, Electron-transport layer materials (ETL), Hole-blocking layer materials (HBL), Organic light-emitting diode (OLED), Organic electronics.

Applications

Bis(10-hydroxybenzo[h]quinolinato)beryllium, known as Bebq2, is the brother of Bepp2 in the Beryllium complex family. It is also a blue-fluorescence emitter with excellent charge transport ability. When compared with Alq3 as an electron-transport material, Bebq2 was proven to be superior, even though the ionisation potential and optical band gap of Bebq2 (5.5 eV and 2.7 eV respectively) and Alq3 (5.6 eV and 2.8 eV respectively) are almost the same. The best use for Bebq2 is not as an emitting-layer material or a host material (even though it is a widely used host material), but as an electron-transport material.
