Patent ID: 8754188

Claim:
An electronic, optical or optoelectronic device comprising a polymeric semiconductor component, the polymeric semiconductor component comprising a polymer having formula (I): wherein: R 1 and R 2 independently are a C 1-20 alkyl group or a C 1-20 haloalkyl group; Ar 1 and Ar 2 independently are an optionally substituted C 6-14 aryl group or an optionally substituted 5-14 membered heteroaryl group; π is an optionally substituted polycyclic aryl or heteroaryl group; m 1 and m 2 independently are 0, 1, 2, 3 or 4; p is 0 or 1; x and y are real numbers representing mole fractions, wherein 0<x≦1, 0≦y<1, and the sum of x and y is about 1; and the polymer has a degree of polymerization in the range of 5 to 10,000.
