The benefits of using hexa-alkoxytriphenylenes as hole transport materials for two-layer light-emitting diodes are reported. Both low molecular weight and polymeric triphenylenes are investigated. The polyacrylate shown in the figure is demonstrated to have excellent film-forming properties and combines sufficient charge carrier mobility with good hole injection properties to make it a very suitable hole transport material.
