Organic light‐emitting diodes (OLEDs) represent a new technology for a future generation of flat‐panel displays. Over the years, significant efforts have been invested towards developing light emitters for the primary colors red, green, and blue to display the RGB signal. In the Full Paper on page 4523 ff., P. Anzenbacher, Jr., et al. demonstrate how effective modification of one of the most prominent OLED materials, tris(quinolinolate) aluminum( III ) (Alq 3 ), results in tuning of its HOMO/LUMO energy levels, which is essential for using Alq 3 derivatives as host materials for various dopants and for tuning the color of the light emitted by the devices.
