Polarized electroluminescence from an anisotropic nematic network on a non-contact photoalignment layer

Polarized electroluminescence from a uniformly aligned nematic network, for med by photopolymerization of a LC monofluorene with diene end-groups (see Figure), is reported. It is shown that macroscopic orientation of the chrom ophore is achieved with a photoalignment layer doped to allow hole transpor t. Thus standard photolithography can be used to make polarized, patterned, multilayer organic electroluminescent displays.
