Abstract
An electronic device comprises a semiconducting polymer of Formula (I): wherein 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; Ar is independently a conjugated divalent moiety; a is an integer from 1 to about 10; and n is an integer from 2 to about 5,000. The electronic device may be an organic thin film transistor.

An electronic device comprising a semiconducting layer, wherein the semiconducting layer comprises a semiconducting polymer of Formula (I):
- wherein 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;
- a is an integer from 1 to about 10;
- n is an integer from 2 to about 5,000;
- and
- each Ar is a conjugated divalent moiety selected from:
- and combinations thereof, wherein R′ is independently selected from hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, heteroaryl, or —CN;
- and the divalent moiety may be substituted peripherally with alkyl, substituted alkyl, aryl, substituted aryl, heteroaryl, halogen, —CN, or —NO2.
An electronic device comprising a semiconducting layer, wherein the semiconducting layer comprises a semiconducting polymer of Formula (I):
- wherein 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,
- each Ar is independently selected from:
