The facile solid-state polymerizable selenophene-based monomer, 3,4-propylenedioxyselenophene (ProDOS), was newly synthesized for highly conductive polyselenophene. Gentle heating (40-80 oC) of crystalline 2,5-dibromo-3,4-propylenedioxyselenophene (DBProDOS) afforded a highly conducting, bromine-doped poly(3,4-propylenedioxyselenophene) (PProDOS), as confirmed by FT-IR, CV, EA, and UV-Vis-NIR spectroscopies. The properties of solid-state polymerized PProDOS were compared with that of the chemically and electrochemically synthesized PProDOS. The solid-state polymerization was studied using DSC, SEM, and gravimetric analysis. The conductivity of the solid-state polymerization depended on the polymerization temperature of PProDOS that reveals a slight thermal activation. Herein we report the synthesis methods of monomer and polymer in detail, and the optical and electrical properties of conductive polymer will be presented. |
