[OLED5-3] Analysis of Deteriorated Species of ETL Generated with Metal Electrode Deposition by Liquid Extraction Surface Analysis Nanoelectrospray Ionization Mass Spectrometry
organic light emitting diode, damage due to electrode deposition, metal organic interface, Alq3, TPBi
The chemical species formed on the ELT caused by the electrode deposition are analyzed by liquid extraction surface analysis (LESA) nano ESI-Orbitrap MS. N-oxygenated and N-hydrogenated molecules of 8-hydroxyquinoline and Alq3 with a wide range of N values and generation of several decomposition components on TPBi are detected and characterized.
