Charge Transport Layer Materials, Fluorescent Host Materials, High Purity Sublimed Materials
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.
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.
