Abstract

The conformations and aggregated structures, such as molecular orientations, of organic molecules in organic lightemitting diodes (OLEDs) are considered to be closely related to the performance of OLEDs. Therefore, their clarification is of great importance in understanding device performance; however, the structures have not been fully analyzed because the organic molecules in OLEDs are often in amorphous states, and conventional methods for structure analysis, such as diffraction methods, do not provide sufficient information. In this study, we have attempted the analysis of molecular orientations of OLED materials by solid-state NMR, which is useful for structure analysis even for amorphous solids.
