Abstract: Efficient synthetic strategies are described for the preparation of rodlike polyelectrolytes based on the intrinsically rigid poly( p ‐phenylene). Uncharged precursors were first prepared via the Suzuki coupling and then characterized by different methods of polymer analysis. Finally, they were transformed into polyelectrolytes using macromolecular substitution reactions. Depending on the substitution pattern, the obtained polyelectrolytes are either soluble or insoluble in water. Using water‐soluble derivatives, the Poisson‐Boltzmann cell model was tested by osmotic measurements and small‐angle X‐ray scattering. It is shown that the cell model provides a good first approximation of the distribution of the counterions around the macroion but still underestimates their correlation. Moreover, the PPP polyelectrolytes show a very pronounced polyelectrolyte effect. Since the rodlike PPPs are very rigid in shape, this observation proves that the polyelectrolyte effect is caused by long‐range intermolecular electrostatic repulsion of the dissolved macroions rather than due to conformational changes.

Abstract: A description of the syntheses of two structurally well‐defined aromatic polyesters having polar 3‐hydroxypropyl or 3‐acetoxypropyl side groups is given. The hydroxy derivative was prepared by reacting a soluble precursor polyester bearing 2‐propenyl substituents with 9‐borabicyclo‐[3.3.1]nonane, followed by an oxidative work‐up procedure. The acetoxy‐substituted polyester was obtained treating the hydroxy polymer with acetic anhydride. The reaction conditions for these steps were studied in detail by using model compounds to minimize cleavage of the ester bonds during the conversions. The analysis of the polyesters by NMR spectroscopy and osmometry proved that under suitable conditions almost no degradation occurs during the conversions of the polyesters.
