CzSi Usage And Synthesis

Description

CzSi is known for its high triplet energy, wide band-gap, and high glass-transition temperature (Tg >131 °C). It is one of the most widely-used TADF host materials for blue electrophosphorescence.

Uses

Carbazole-based host materials for blue electrophosphorescence.
