White Light from Excimer and Electromer in Single-Emitting-Component Electroluminescent Diodes

A series of highly fluorescent, fluorinated carbazole derivatives have been synthesized and fully characterized. "Pure" white light consisting of a blue light from excimers and an orange light from electromers at a high voltage has been achieved by using these compounds as single-emitting components in organic light-emitting diodes (OLEDs).
