Application

CzTrz exhibits good film-forming properties, high charge carrier mobility, and excellent triplet energy level compatibility with a wide range of phosphorescent and fluorescent dopants. These characteristics contribute to efficient charge recombination and emission of high-quality light in organic light emitting diodes (OLEDs). It can act as a hole-transporting material in the active layer of OFET devices, enabling efficient charge transport and modulation of conductivity.
Dopant for Light Blue Thermally Activated Delayed Fluorescence (TADF) OLED with EQE of 25%.
