Abstract

To create polarized organic light emitting diodes (OLEDs), liquid-crystalline polymers (LCPs) containing oxadiazole and amine moieties in the side chain were design and synthesized. These LCPs emitted intense blue fluorescence with high quantum yield over 0.6 in a solution. Furthermore, polarized emissions of fluorescence were observed in a LC phase, and order parameters estimated by the polarized emission were about 0.2. They have proven to function as polarized blue-emitting materials for OLEDs.
