A semiconducting polymer of Formula (1):n nwherein X is independently selected from S, Se, O, and NR, wherein R is independently selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, heteroaryl, and-CN; nAr is independently a conjugated divalent moiety; na is an integer from 1 to about 10; and nn is an integer from 2 to about 5,000. n The resulting semiconducting polymer is suitable for use in organic thin film transistors. |
