Abstract

The synthesis, characterization, and solid-state structure of new thiophene-based alternating π-conjugated polymers containing the 4-alkyl-1,2,4-triazole or 1,2,4-thiadiazole unit as per partner unit were reported. A new thiophene-based CT type alternating copolymers was synthesized to obtain further scope about the packing structure and chemical properties of such CT type alternating π-conjugated copolymers. It was observed that the difference between the syn and anti conformations was small. It was also observed that the calculated density (1.79 g cm-3) according to the packing model agreed with the observed density (1.73 g cm-3).
