| Full-color organic light-emitting diode (OLED) devices comprise red, green, and blue electroluminescent pixels. Each color pixel has an emitting layer containing a different fluorescent dopant. The practical emitting lifetime for the blue layer of such displays is shorter than those of the green and red layers. Over time this deficiency leads to a shift in display color balance and a decrease in the brightness. A common blue-emitting layer is TPB doped into the host material TBADN. The use of alternative dopants can lead to different device lifetimes and emission colors. The synthesis and use of difluoroboron bis(azinyl)amines (1), a new class of dopant materials, has led to devices that show improved blue color and greater device stability. A newly developed synthesis allows for differentially substituted azinyl rings in these compounds.
