Abstract
NIR OLEDs are achieved by blending ethyne-linked zinc(II) porphyrin pentamers into a red-emitting push–pull polymeric host matrix (PIDT-2TPD). We report external quantum efficiencies of 2.0 % with peak emission at 830 nm, confirming the promise of porphyrin oligomers for non-toxic NIR OLEDs.
