Strong Anionic Fluorene Donor-Acceptor Copolyelectrolytes from Protected Hydrophobic Precursors.

ABSTRACT: Conjugated polyelectrolytes (CPEs), materials that are defined by a π$\pi$ -conjugated backbone and charged ionic functional groups, are frequently prepared through direct polymerization of charged monomer species in aqueous media. This route is, however, often accompanied by labor-intensive work-up procedures, low yields, and ultimately results in materials that are difficult to characterize. To overcome these inconveniences, in this work protection chemistry is applied on sulfonate-functionalized fluorene monomers that are polymerized under standard Suzuki polycondensation conditions to obtain protected donor-acceptor copolymers. Treatment of the organo-soluble precursors under nucleophilic conditions resulted in quantitative removal of the protecting groups, thereby exposing the strong
