A series of new rigid rod-like molecules consisting of a dibenzosilole core, ethynylene linkages, and different aryl end-groups has been synthesized by palladium-catalyzed Sonogashira cross-coupling reactions. These compounds exhibit intense blue to green emissions with high quantum efficiencies and good thermal stabilities.
