Near-Infrared Organic Light Emitting Diodes based on Porphyrin Oligomers

摘要

We report the optical characterisation of a series of near-infrared emitting porphyrin oligomers incorporated in polymer light-emitting diodes. We study the photoluminescence in solutions and films, and the electroluminescence of the oligomers in blends with poly(9,9'-dioctylfluorene-a/f-benzothiadiazole) that demonstrated high external quantum efficiency.
