Effect of strong acid on the self-oscillating behavior for the polymer chain with the Fe(bpy)(3)

In this study, a self-oscillating polymer chain with Fe(bpy)(3) as the catalyst of the Belouzov-Zhabotinsky (BZ) reaction was synthesized to examine the influence of strong acid (due to its oxidizing power) on the self-oscillating behavior. The polymer chain with Fe(bpy)(3) underwent a soluble-insoluble self-oscillation induced by the BZ reaction because the solubilities of the Fe(bpy)(3) moiety in the reduced and oxidized states were different. The self-oscillation of the polymer chain with Fe(bpy)(3) lasted a long time. During the long period of the self-oscillation, the oscillating period and amplitude of the self-oscillation were stable.
