Researchers from Canada's Polytechnique Montréal and the Université de Montréal developed a new near-infrared (840 nm) TADF OLED device that is 300% more efficient than existing ones. The IQE of the new deice is 3.8% - which is the best all-organic OLED emitter ever developed above 800 nm.

To create the new OLED device, the researchers developed two new organic compounds - and were inspired by a class of molecules previously used for biomedical imaging.
