The use of aqueous or aqueous methanolic ionene (cationic polyelectrolytes consisting of dimethylammonium charge centers interconnected by alternating alkyl chain segments containing x and y methylene groups) solutions as mobile phases in thin layer chromatography (TLC) is described. The ortho, meta and para isomers of chlorobenzoic acid and phenylphenol as well as dinitroanilines and 1- and 2-naphthol were successfully chromatographed using aqueous solutions of [3, 16]-ionene with polyamide thin layer sheets. Some quinones were successfully resolved using this same aqueous ionene mobile phase but with cellulose thin layer plates. For some analytes, the TLC retention results obtained with the [3, 16]-ionene were compared to that obtained with [3, 6]-ionene, which does not form intramolecular aggregated species. The relevant properties of micelle-mimetic intramolecular ionene aggregates are described as are their possible advantages over conventional normal surfactant micelle systems. A brief prospectus on the future use of such micelle-mimetic ionene aggregates in separation science is presented.
