在一个实施例中，聚合物包括由显示在下方之式(1)表示的重复单元。该聚合物之重量平均分子量在3000或更大至1000000或更小之范围内。;R1表示选自氢、经取代或未经取代之烷基、经取代或未经取代之芳族基及经取代或未经取代之杂芳族基之单价基团。R2、R3及R4独立地表示选自氢、卤素、经取代或未经取代之烷基、经取代或未经取代之烷氧基、经取代或未经取代之芳族基及经取代或未经取代之杂芳族基之单价基团。X、Y及Z独立地表示选自O、S及Se之原子。;R1 indicates a monovalent group selected from hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic group, and a substituted or unsubstituted hetero-aromatic group. R2, R3, and R4 indicate independently a monovalent group selected from hydrogen, halogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aromatic group, and a substituted or unsubstituted hetero-aromatic group. X, Y, and Z indicate independently an atom selected from O, S, and Se. |
