General description

TSPO1 is an electon transfer layer (ETL) or hole blocking layer (HBL) in OLED devices.

Application

TSPO1 is a phosphine oxide-based blocking and host material with triplet energy excitons. It is mainly used in the formation of a blocking layer that enhances the performance of organic electronic devices like organic light-emitting diodes (OLEDs), and delayed fluorescent devices.
