摘要

Triarylamine derivatives are widely used as hole-transport materials in various fields such as in organic electroluminescent (EL) devices. Normally, in EL devices molecular materials are required in an amorphous state, so that the injected electrons and holes can be confined in the amorphous layer for efficient EL emission. However, molecular materials with high crystal-linity are required for organic field-effect transistors (OFETs), so that the semiconductor layer contains as few defects (e.g., disorders, grain boundaries) as possible, that is, the mobility of the molecular materials is as high as possible. The different requirements limit the application of triarylamine derivatives in OFETs.
