The rational design of a new series of charge-neutral Ru(II) metal complexes is reported here. Ruthenium complexes with isoquinolyl ligands have been utilized as dopant emitters for the fabrication of red and red-orange OLEDs (see figure). The high efficiencies and low turn-on voltage obtained using inexpensive Ru marks a significant advance in the field of organic displays.
