Influence of a Positively Charged Moiety on Aggregation-Disaggregation Self-Oscillation Induced by the BZ Reaction

The behavior of the transmittance self-oscillation of a polymer chain with a positively charged MAPTAC group is studied. The polymer concentration exerts considerable influence on the behavior and lifetime of the self-oscillation. The redox potential and transmittance are measured simultaneously showing that the reactivity of the Ru(bpy)(3) moiety is significantly affected by the polymer aggregation state, originating from the solubility of the polymer chain. The behavior and lifetime of the self-oscillation can be controlled by changing the design of the polymer structure and concentration.
