A novel family of amorphous molecular materials containing an oligothiophene moiety as color‐tunable emitting materials for organic electroluminescent devices
Source abstract
Abstract
The color of light emitted by organic electroluminescent devices can be tuned between light blue and orange in the family of materials presented here simply by varying the conjugation length (n = 1 to 4, see Figure) of the oligothiophene moiety. The synthesis of the amorphous molecular materials and the optical behavior of single‐layer electroluminescent devices based on them—see also the cover—are described.magnified image
