3-(Biphenyl-4-yl)-5-(4-tert-butylphenyl)-4-phenyl-4H-1,2,4-triazole Usage And Synthesis

Applications

1,2,4-triazole-based 3-(biphenyl-4-yl)-5-(4-tertbutylphenyl)-4-phenyl-4H-1,2,4-triazole (TAZ) (ET: 2.7 eV, HOMO/LUMO: 6.3/2.7 eV) has mostly been used in blue phosphorescent OLEDs (PhOLEDs) to serve as an efficient electron-transporting and hole-blocking layer due to its high triplet energy level that would confine the triplet excitons within the emissive layer.
The low HOMO/LUMO energy level of TAZ is beneficial for blocking holes and facilitating electron injection/transport, thereby enhancing the device performance.

Description

1,2,4-triazole-based 3-(biphenyl-4-yl)-5-(4-tertbutylphenyl)-4-phenyl-4H-1,2,4-triazole?(TAZ) (ET: 2.7 eV,?HOMO/LUMO: 6.3/2.7 eV) has mostly been used in blue phosphorescent OLEDs (PhOLEDs) to serve as an efficient electron-transporting and hole-blocking layer due to its high triplet energy level that would confine the triplet excitons within the emissive layer.

Uses

OLED and QD-LED electron transporter and hole blocker material.
