Abstract :

 Asymmetric (4a–g) antracene–based conjugated compounds comprising electron rich aromatic building blocks were designed and successfully synthesized by the palladium–catalyzed Suzuki coupling and finally by Knoevenagel method. These compounds have a relatively small band gaps and show strong absorption in the region 350–520 nm. Furthermore anthracene based compounds show the light emission in the region from violet to yellow. The electrochemical behavior of synthesized structures was confirmed by EPR as well as theoretical quantum chemical approaches. The calculations rationalize the difference between electrochemical and optical experimentally measured energy gaps.
