Abstract

In this paper the monodomain-alignment of new photocrosslinkable fluorene bisacrylate model compounds and oligomers is reported. The orientation of the nematic LC-phase is preserved by photopolymerization in an oriented LC-network. Monodomain orientations of crosslinked fluorene bisacrylates are investigated by UV-VIS and photoluminescence spectroscopy comparing different alignment layers. OLEDs were fabricated using oriented fluorene bisacrylates and polyfluorenes leading to state-of-the-art polarization ratios for electroluminescence of up to 25 and brightnesses of about 250 Cd/m2.
