High Purity TAZ (C30H27N3) for OLED Application, 99%, 1g

3-(Biphenyl-4-yl)-5-(4-tert-butylphenyl)-4-phenyl-4H-1,2,4-triazole (TAZ), which is a triazole derivative having 4 phenyl rings and a triazole core, is commonly used as electron transport materials due to high electron injection. It has been shown to have effective electron injection and hole blocker effect. It has mostly been used in blue phosphorescent OLEDs to serve as an efficient electron-transporting and hole-blocking layer for its high triplet energy level (2.75 eV) that would confine the triplet excitons within the emissive layer; it has also been employed as an efficient electron-transporting host for green PHOLEDs.
