bis[2-(2-Pyridinyl)phenolato]berylliuM

Description

Bis[2-(2-hydroxyphenyl)-pyridine] beryllium, known as Bepp2, belonging to the beryllium complex family, is a blue fluorescence?emitter with excellent charge transport ability. Due to its high electron mobility and high triplet energy level, Bepp2 has been used as an electron-transporting and?hole/exciton-blocking layer material in OLEDs. High-efficiency blue OLEDs by using Bepp2 as the emitting layer material and high efficiency white OLEDs using Bepp2 as host material have been achieved [1-8].

General Description

Blue OLED dopant material.
