Near-infrared emitters (NIR) will be of crucial importance for a variety of biomedical, security and defense applications, as well as for (in)visible light communications and the internet-of-things (IoT). Researchers from the UK and Italy have developed porphyrin oligomer NIR emitters which afford high efficiencies despite being totally free from heavy metals. They demonstrated organic light-emitting diodes (OLEDs) at 850 nm with 3.8% peak external quantum efficiency, together with a novel quant...
