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.
