Abstract

2-Thienyl- and 2,2’-bithienyl-5-yltropylium ions, as well as 2,5-thienylenebis(tropylium), 2,2’-bithienyl-5,5’-diylbis(tropylium), and 2,2’:5’,2":5",2’’’-quaterthienyl-5,5’’’-diylbis(tropylium) ions have been synthesized and their electronic structures in the ground and excited states have been clarified.
