Abstract
The diffusion behavior of the conjugated polyelectrolyte poly{[9,9-bis(6'-N,N,N-trimethylammonium)hexyl]fluorene-phenylene) bromide (HTMA-PFP) with different molecular weights has been studied in dimethyl sulfoxide (DMSO) + water solutions. Samples of HTMA-PFP with various molecular weights were obtained by synthesis of poly[9,9-bis(6'-bromohexyl)fluorene-phenylene] via a Suzuki coupling reaction, characterized by size exclusion chromatography (SEC), and quaternized with trimethylamine. Multicomponent chemical interdiffusion coefficients (mutual diffusion coefficients) were determined for solutions of HTMA-PFP and DMSO in water using the Taylor dispersion method. The results suggest specific interactions between the DMSO and the polymer.... (More)

The results suggest specific interactions between the DMSO and the polymer. In addition, these systems were studied by pulse-field gradient nuclear magnetic resonance spectroscopy (PFG-NMR), and the corresponding self-diffusion coefficients were obtained. These were modeled using the Kirkwood-Riseman model, and a good fit to the observed behavior was obtained using literature data for molecular dimensions. (Less)
