The photoluminescence and electroluminescence of guest–host blends containing DD and DDD (see Figure) in the conjugated polymers polyvinylcarbazole (PVK) and poly[2‐methoxy‐5‐(2′‐ethylhexyloxy)‐1,4‐phenylenevinylene] (MEH‐PPV) is described. It is shown that this class of long‐wavelength‐emitting porphyrin oligomer, is an excellent platform upon which to fabricate near‐infrared light‐emitting devices.
