摘要: Synthetic methods have been developed for the preparation of new 2,3-dihalo- and 2,3-ditriflato-5,7-bis(2-thienyl)thieno[3,4-b]pyrazines. From these reactive intermediates, a variety 2,3-difunctionalized 5,7-bis(2-thienyl)thieno[3,4-b]pyrazines produced as precursors to conjugated materials. Structural, electronic, optical characterization analogues illustrate extent which electronic nature functional groups can be used tune properties thieno[3,4-b]pyrazine-based terthienyl units.
