Organic Light Emitting Diode (OLED) are widely used to digital display in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles and personal digital assistances. Also, because of thin, light and flexible properties, OLED is drawing attention as the upcoming-generation material. For the applications, identification of side-materials in well-established OLED complexs is a very important for its purity and stability analysis. In this study, three iridium emitters and one material of photonic and optical device were identified by supercritical fluid chromatography (SFC) and reversed-phase ultra performance liquid chromatography (UPLC) coupled to electrospray ionization (ESI) Mass Spectrometry at the molecular level. SFC utilizes supercritical carbon dioxide, methanol as mobile phase and offers a faster runtime in comparison with UPLC and minimization of noise peaks in baseline for purity analysis in OLED samples. Overall, SFC- and UPLC-MS was successfully applied to OLED compounds for compositional and purity elucidation. Therfore, these results are examples of using powerful separation technique in the field of OLED and we expect that this developed technique will be involved in the actual OLED process.
