Synthesis of substituted conjugated polymers: Tuning properties by functionalization

The review addresses features of special interest concerning two classes of functionalized semiconducting polymers: poly(aryleneethynylene)s (PAEs) bearing biomolecules as chiral nonracemic pendant groups and poly(phenylenevinylene)s (PPVs), which are fluorinated in various positions of the repeating units. Molecular design and choice of specific substituents, synthetic protocols. and the effect of functionalization on properties of the polymers both in solution and in the solid state are discussed.
