Abstract

Micellar solutions of cetyltrimethylammonium sulfate dramatically reduce the amplitude and lengthen the induction period of the Ru(bpy)32+-catalyzed Belousov-Zhabotinsky oscillations compared to reaction in aqueous solution, whereas micellar solutions of sodium lauryl sulfate shift oscillations to higher absorbances with a longer oscillation period but no change in the induction period. The ability of micelles to selectively compartmentalize ions and molecules may account for their effects on the amplitude and period of the BZ reactions.
