A polymer comprises a polymeric chain represented by formula (I) or (II). In formula (I), a, b, c, d, and n are integers, a from 0 to 3, b from 1 to 5, c from 1 to 3, d from 1 to 5, and n from 2 to 5000; R1 and R2 are side chains; R3 and R4 are each independently H or a side chain; and when a is 0, R3 and R4 are side chains. In formula (II), a, b, c, d, e, and n are integers, a from 1 to 3, b and c being independently 0 or 1, d and e being independently 1 or 2, and n from 2 to 5000; R1 and R2 are side chains except —COOalkyl; and X1, X2 and X3 are independently O, S, or Se. Semiconductors and devices comprising the polymer are also provided.
一种聚合物包括由公式(I)或(II)表示的聚合物链。在公式(I)中,a,b,c,d和n是整数,a从0到3,b从1到5,c从1到3,d从1到5,n从2到5000; R1和R2是侧链; R3和R4各自独立为H或侧链; 当a为0时,R3和R4是侧链。在公式(II)中,a,b,c,d,e和n是整数,a从1到3,b和c分别独立为0或1,d和e独立为1或2,n从2到5000; R1和R2是侧链,除了-COOalkyl; X1,X2和X3独立地为O,S或Se。还提供了包括该聚合物的半导体和器件。
