Abstract

Two new fluorenone-based conjugated polymers, F1 and F2, were synthesized via the Stille cross-coupling polymerization. Spectral measurements showed that both polymers had optical band gaps of 1.99 eV and 1.89 eV, respectively, calculated based on the film onset absorption edge. Cyclic voltammetric studies gave HOMO/LUMO energy levels of -5.18 eV/-3.19 eV and -5.40 eV/-3.51 eV, respectively, and the polymers were thermally stable at temperatures over 300 °C. Organic field-effect transistor and bulk-heterojunction solar cell performance characteristics of both polymers as p-type semiconductors were evaluated.
