In this study, we report the activation energy of the optical self-oscillation for a polymer chain that consisted of N-isopropylacrylamide (NIPAAm) (25 wt%), the Ru catalyst (5 wt%) of the Belouzov-Zhabotinsky (BZ) reaction, and acrylamide-2-methylpropanesulfonic acid (AMPS) (75 wt%). The AMPS moiety in the polymer chain has a negative charge and works as a solubility control site in the self-oscillating polymer chain (poly(NIPAAm-co-Ru(bpy) ₃-co-AMPS)). The optical self-oscillation of the polymer chain at constant temperature was induced by the BZ reaction. In the BZ reaction, the Ru(bpy)₃ moiety in the polymer chain undergoes redox oscillation, and at the same time, the solubility of Ru(bpy)₃ changes periodically. Due to the cyclic redox change in the Ru(bpy) ₃ moiety, the polymer chain underwent soluble-insoluble self-oscillation. The period of the self-oscillation for the poly(NIPAAm-co-Ru(bpy) ₃-co-AMPS) decreased with increasing temperature, in accordance with the Arrhenius equation.
