Abstract

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 of new 2, 3-difunctionalized 5, 7-bis (2-thienyl) thieno [3, 4-b] pyrazines have been produced as precursors to conjugated materials. Structural, electronic, and optical characterization of these new analogues illustrate the extent to which the electronic nature ...
