| 제목 | Synthesis and Characterization of Thienopyrrolodione-Based Copolymers and Their Application in Organic Thin-Film Transistors |
| 초록 | Two thienopyrrolodione (TPD)-based polymers, 24DTT-TPD and 24DTS-TPD, were synthesized by carrying out Stille coupling reactions. The obtained polymers were characterized by 1H NMR, FT-IR, mass analysis, UV-visible spectroscopy, cyclic voltammetry, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The deposited films were characterized by X-ray diffraction. Synthesized polymers showed good solubility in common solvents. The solution-processed organic field-effect transistors showed field-effect mobility values of 45×10−5 cm2/Vs for 24DTT-TPD and 29×10−2 cm2/Vs for 24DTS-TPD at optimal conditions. In summary, we successfully synthesized and characterized two new D-A conjugated polymers: 24DTS-TPD and 24DTT-TPD. Examination of thermal properties of 24DTS-TPD and 24DTT-TPD revealed that the two polymers have good thermal stability. |
