Application

Carbazole-based host materials for blue electrophosphorescence.
CzSi is a host material with tetrahedral Si atoms that act as effective spacers and thereby block the π conjugation of the carbazole core. It is used as a hole transporting molecule (HTM) that is mainly used in the development of organic light-emitting diodes (OLEDs). CzSi can also be used in the formation of a blue electrophosphorescence.
