Triaryl amine thick layer doped with metal amides for use as HIL for an organic light-emitting diode (OLED)

摘要

The present invention relates to a hole injection layer for an OLED comprising a triarylamine compound doped with a charge neutral metal amide compound, characterized in that the hole injection layer has a thickness of at least about ≥20 nm to about ≤1000 nm and the charge neutral metal amide compound has the Formula Ia.;
