Abstract:

Here we report on organic light-emitting diodes incorporating two porphyrin compounds exhibiting red to near infra-red (IR) emission. Especially, the compound with the long side groups (porphyrin II) has a red-shifted emission (λPLmax = 793 nm) compared to the compound with the single porphyrin ring (porphyrin I, (λPLmax = 723 nm) as a consequence of its extended π-conjugation. We studied the electroluminescence of blends with poly(9-vinyl carbazole) (PVK), achieving high color purity near-infrared electroluminescence.
