By the molecular structure construction of conjugated polymers based on molecular design, it is possible to properly tune their physical properties such as solubility, electronic and optical properties. We have reported the series of conjugated polymers having an oxadiazole group in the main chain. In this presentation, we report the synthesis and characterization of polyoxadiazoles having a thiophene group adjacent to oxadiazoles. Thiophene is known as a π-excessive heterocyclic, whereas an oxadiazole is known as π-deficient one. So the newly synthesized polymers are expected to show enhanced charge transfer characteristics. The resulting polymers show blue fluorescence in a solution (426 nm). However, in films, their fluorescence colors turn to weak greenish-blue (450 nm). Details of synthesis, structural characterization and physical properties of the polymers will be presented. |
