HIGH ENERGY TRIARYLAMINE COMPOUNDS FOR HOLE TRANSPORT MATERIALS

摘要

This invention relates to triarylamine compounds and compositions including such compounds, that are useful in electronic applications. It also relates to electronic devices in which the active layer includes such a compound or composition. The triarylamine compound can be present as a hole transport material in a hole transport layer. The triarylamine compound can also be present in a photoactive layer in combination with an organometallic compound capable of electroluminescence having an emission maximum between 380 and 750 nm.
