Abstract

Using a "multifluorination" strategy, ambipolar donor-acceptor conjugated polymer with hole and electron mobility (μ_h and μ_e ) up to 3.94 and 3.50 cm² V^-1 s^-1 , respectively, and unipolar n-type donor-acceptor conjugated polymers with μ_e up to 4.97 cm² V^-1 s^-1 is synthesized with isoindigo as acceptor units.

Keywords: conjugated polymers; electron transport; fluorination; isoindigo; organic field-effect transistors.
