摘要：

Polarized electroluminescence is observed for a uniaxially aligned sample of a discotic compound in its crystalline state. The alignment was achieved by coating the ITO anode with an aligned film of poly( tetrafluoroethylene) ( PTFE) deposited using the friction method. Organic light emitting devices with the layer sequence glass/ITO/PTFE/tetraethyl perylene-3,4,9,10- tetracarboxylate (55 nm)/ aluminium (100 nm) show linearly polarized emission of light with a dichroic ratio up to 3.2.
