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 4.5×10-5 cm2/Vs for 24DTT-TPD and 2.9×10-2 cm2/Vs for 24DTS-TPD at optimal conditions.
通过进行Stille偶联反应,合成了两种基于噻吩吡咯二酮(TPD)的聚合物,即24DTT-TPD和24DTS-TPD。所获得的聚合物通过1H NMR、FT-IR、质谱分析、紫外-可见光谱、循环伏安法、差示扫描量热法(DSC)和热重分析(TGA)进行了表征。沉积的薄膜通过X射线衍射进行表征。合成的聚合物在常见溶剂中显示出良好的溶解性。溶液法制备的有机场效应晶体管在最佳条件下显示出场效应迁移率值,24DTT-TPD为4.5×10-5 cm2/Vs,24DTS-TPD为2.9×10-2 cm2/Vs。
