3-Alkylthieno[3,2-b]thiophene and 3-alkyl-6-bromothieno[3,2-b]thiophene derivatives were synthesized and characterized. 3-Bromothiophene or 3,4-dibromothiophebe was selectively acylated via Friedel-Craft method and cyclized followed by nucleophilic substitution reaction to afford 3-alkylthieno[3,2-b]thiophene or 3-alkyl-6-bromothieno[3,2-b]thiophene derivatives respectively. The latter was further manipulated into aryl substituted moiety by transition metal-catalyzed reactions. The resulting monomers were then polymerized via metal–catalyzed cross-coupling methods especially developed by McCullough and Rieke methods. The resulting conjugated polymers were characterized by UV-vis, Fluorescence, and electrochemical methods.
