Infrared held in a pincer

Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team has now developed the first chromium complex that emits light in the coveted, longer wavelength NIR-II range. The team has introduced the underlying concept: a drastic change in the electronic structure of the chromium caused by the specially tailored ligands that envelop it.
