摘要
We demonstrated that triazine (TRZ) derivatives possessing metal coordination sites in their structures showed excellent electron transport and injection characteristics in transparent organic light emitting diodes (TOLEDs). High luminescence efficiency with low driving voltage was observed with a TRZ/ITO cathode configuration (ITO: indium-tin-oxide), suggesting that the TRZ layer can efficiently accept electrons from the metal-oxide cathode layer, and inject electrons into an adjacent organic layer.
