Red and near infrared polarized light emissions from polyfluorene copolymer based light emitting diodes
Journal article, 2007

The authors report polarized red, electroluminescence peak at 705 nm and near IR, electroluminescence peak at 950 nm, light emission from light emitting diodes based on two polyfluorene copolymers. The copolymers are synthesized from a fluorene monomer combined with donor-acceptor-donor comonomers and designed to have a low band gap and form birefringent liq. cryst. phases. Emission occurs from aligned thin films of polymer layers. The emissive layers are aligned by spin coating on a layer of rubbed conducting polymer poly(3,4-ethylene dioxythiophene)-poly(styrene sulfonate) and thermally converted into glassy nematic liq. cryst. state.
