Application

SF3-TRZ can also be utilized in devices such as organic photovoltaic (OPV) devices and organic field-effect transistors (OFETs). In OPV devices, it can serve as an electron transport or electron-blocking material, assisting in efficient charge extraction and collection. In OFETs, SF3-TRZ can act as an electron-transport layer, enabling the smooth flow of electrons in the device. It can be used as an electron-transport layer in organic light-emitting diodes (OLEDs), facilitating the efficient injection and transport of negative charges (electrons) from the cathode to the emissive layer.
Use as TADF Host for Green TADF OLED, EQE of 20.6%.

Organic light-emitting diodes have become a mainstream display technology because of their desirable features. Third-generation electroluminescent devices that emit light through a mechanism called thermally activated delayed fluorescence are currently garnering much attention. However, unsatisfactory device stability is still an
