Abstract:

Blue poly(phenylene-ethynylene) (PPE) electroluminescence is achieved in a single layer organic light emitting device. The polymeric system consists
of an oxadiazole grafted PPE, which combines the necessary charge
transport properties while maintaining the desirable efficient, narrow
light-emitting properties of the PPE. Incorporation of a pentiptycene
scaffold within the PPE structure prevents ground-state and excited-state
interactions between the pendent oxadiazole units and the conjugated
backbone.
