New material concept allows more cost-effective production of blue organic light-emitting diodes

Blue organic light-emitting diodes (OLEDs), which can be used in smartphones, televisions or other devices, are still difficult to manufacture today. A team of researchers led by Gert-Jan Wetzelaer of the Max Planck Institute for Polymer Research has now developed a new material concept that allows blue OLEDs to be manufactured easily and cost-effectively.
