Near-infrared light-emitting diodes based on solution-processed semiconductors, such as organics, halide perovskites and colloidal quantum dots, have emerged a viable technological platform for biomedical applications, night vision, surveillance optical communications. The recently gained increased understanding of the relationship between materials structure photophysical properties has enable...

Abstract The energy gap law ( E G -law) and aggregation quenching are the main limitations to overcome in design of near-infrared (NIR) organic emitters. Here, we achieve unprecedented results by synergistically addressing both these limitations. First, propose porphyrin oligomers with increasing length attenuate effects -law suppressing non-radiative rate growth, increase radiative via enhance...
