CAS Number 898546-82-2
CzSi is a TADF host material 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 electro-phosphorescence.
It possesses bulky, sterically-hindered triphenylsilyl substitutions on electrochemically-active C3 and C6 positions of carbazole. With a nearly-perfect 90° dihedral angle between its carbazole and tert-butylphenyl groups, CzSi exhibits enhanced morphological and superior electrochemical stability.
