| Hazard Information | Back Directory | [Description]
TSPO1, diphenyl[4-(triphenylsilyl)phenyl]phosphine oxide, has a structure of triphenylsilane connecting triphenyl?phosphine oxide. Comparing with UGH-2, TSPO1 has?large permanent dipole moment due to the polar phosphine oxide group and its asymmetric?structure. | [Uses]
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. | [General Description]
TSPO1 is an electon transfer layer (ETL) or hole blocking layer (HBL) in OLED devices. |
