Abstract

We showed that tetra-2-pyridinylpyrazine (TPP) and TPP: cesium (1:1 molar ratio) composite layers had excellent electron injection and transport characteristics in organic light emitting diodes. High luminescence efficiency with low driving voltage was observed in various cathode configurations, suggesting that the TPP layer can efficiently accept electrons from metal and metal oxide cathode layers, and transport and inject electrons into an adjacent organic layer.
