A novel series of soluble conjugated polymers, poly[1,4-bis(4-alkyl-2-thienyl)-2,5-disubstituted phenylene]s, with different substituents on the phenylene ring (hydrogen, methyl group, or decyloxy group) and on the thiophene ring (n-hexyl chain or cyclohexyl group) were synthesized through FeCl3-oxidative polymerization. The structures of the polymers were fully verified by FT−IR, 1H and 13C NMR, and element analysis. The high regioregularity of head-to-head linkage between two adjacent thiophene rings in the polymers was demonstrated. The electronic spectra of the polymers can be tuned by changing the substitution on both the phenylene and thiophene rings, emitting blue to green light. The electronic structures of the polymers can also be tuned by different substitutions, as demonstrated by electrochemical measurements (cyclic voltammetry). The absolute photoluminescence (PL) efficiencies of the polymers in neat films, which can be remarkably effected by the substitution on both the phenylene ring and th...
