Electronic visual displays have come a long way since the early days of cathode-ray tubes. Modern display devices, based on organic light-emitting diodes (OLEDs), are compact enough to accompany us wherever we go, in portable devices such as smartphones and smartwatches. Still, there is a need for further improvements in the performance of OLED-based displays, especially regarding energy efficiency and color purity, both of which directly impact power consumption. Recently, a team of researchers from the two institutes of the Polish Academy of Sciences (PAS), Institute of Physical Chemistry PAS and Institute of Organic Chemistry PAS, and from the Silesian University of Technology proposed a series of new chemical compounds to serve as the emitters of OLEDs, taking us one step closer towards robust and sustainable technologies in portable electronics.
