Cover Picture: Synthesis and Characterization of a Multicomponent Rhenium(i) Complex for Application as an OLED Dopant (Angew. Chem. Int. Ed. 16/2006)
Modular molecules designed to act as efficient dopants for organic light-emitting diodes (OLEDs) encourage directional transport of electrons and holes, causing them to recombine at the emitting center. In their Communication on page 2582 ff., K. C. Gordon and co-workers describe such a molecule, a phosphorescent dye that comprises an emissive center bound on either side by an electron-transport group and a hole-transport group, as shown in the cover picture.
