UTILIZATION OF MICELLE-MIMETIC INTRAMOLECULAR IONENE AGGREGATES AS THE MOBILE-PHASE IN PSEUDOPHASE THIN-LAYER LIQUID-CHROMATOGRAPHY

The use of aqueous or aqueous methanolic ionene (cationic polyelectrol ytes consisting of dimethylammonium charge centers interconnected by a lternating alkyl chain segments containing x and y methylene groups) s olutions as mobile phases in thin layer chromatography (TLC) is descri bed. The ortho, meta and para isomers of chlorobenzoic acid and phenyl phenol as well as dinitroanilines and 1-and 2-naphthol were successful ly chromatographed using aqueous solutions of [3,16]-ionene with polya mide thin layer sheets. Some quinones were successfully resolved using this same aqueous ionene mobile phase but with cellulose thin layer p lates. 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 properti es of micelle-mimetic intramolecular ionene aggregates are described a s are their possible advantages over conventional normal surfactant mi celle systems. A brief prospectus on the future use of such micelle-mi metic ionene aggregates in separation science is presented.
