Polarized Electroluminescence from an Anisotropic Nematic Network on a Non-contact Photoalignment Layer

Abstract

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