BTB
Product Detail
1. Overview
The rapidly growing field of organic light-emitting diodes (OLEDs) is driven by a diverse array of materials and compounds. Among these, BTB (C34H28N6), formally named 4,4′-Bis(4,6-diphenyl-1,3,5-triazin-2-yl)biphenyl, has established itself as a foundational component in OLED technology.
BTB is mainly used as an electron-transport material in organic light-emitting devices (OLEDs), and as a phosphorescent host material for green and red light-emitting diodes
BTB as the electron transport layer (ETL) exhibit lower driving voltages and higher efficiencies - relative to those incorporating Alq3
