摘要 |
Compounds having a core comprised of an aromatic ring and at least two annulated beta-substituted fused thiophene ring systems of the general formula: -(β-R2-FT2ArFT2-β-R2)-, and polymers or copolymers thereof, of the general formulas: -{-β-R2-FT2ArFT2-β-R2)-G1-}n-, or -{-G1-(β-R2-FT2ArFT2-β-R2)-G1-G2-}n-, whereβ-R2-FT2ArFT2-β-R2, -G1-, -G2-, and n are as defined herein. Also disclosed are compositions, articles, or devices comprising the polymers, and methods for making and using the polymers. The compositions, articles, or devices can be used, for example, for electronic applications, such as light emitting devices and semiconductor devices.
