Abstract
A polymer of Formula (I) wherein Ar, R1, R2, R3, R4, Y, x, k, m, and n are as described herein. The polymer may be used in a semiconducting layer of an electronic device.
Claims20
A polymer of Formula (I):
- wherein each Y is independently O or N—R5, wherein each R5 is independently hydrogen, alkyl, substituted alkyl, aryl, or substituted aryl;
- each R3 and R4 is independently alkyl, substituted alkyl, aryl, substituted aryl, heteroaryl, substituted heteroaryl, halogen, alkoxy, alkylthio, trialkylsilyl, —CN, or —NO2;
- k and m are independently 0, 1, 2, or 3;
- each Ar is independently ethenyl, ethynyl, aryl, substituted aryl, heteroaryl, or substituted heteroaryl;
- x is from 0 to 8;
- and
- wherein n is the number of repeating units and is from 2 to about 5,000.
