Application

Recent advancement in boron-based efficient and pure blue thermally activated delayed fluorescence materials for organic light emitting diodes. This is a sublimed high purity material, used as TADF Blue Dopant, with a EQE of 25.1%.
t-DABNA can be used as a host material or as a hole-blocking material in the emissive layer of OLED devices. Its high triplet energy level and other properties can contribute to efficient exciton management and improved device performance. It can also be used in studies on organic photovoltaic (OPV) devices and organic field-effect transistors (OFETs).

In the last few years, electron-deficient materials have been actively researched for application in organic light-emitting diode (OLED) as dopant and electron-transporting materials. The boron-containing materials are interesting as they give good emissive properties in solid state with an electron-accepting
