Fe(bathophen)2(phen)-based self-oscillating gel driven by the Belousov–Zhabotinsky reaction

The synthesis of a new Fe(bathophen)₂(phen)-based self-oscillating gel driven by the Belousov–Zhabotinsky reaction is described. The gel undergoes spontaneous chemomechanical oscillations without any on–off switching by external stimuli and demonstrates the dependence of chemomechanical behavior on the concentration of the catalyst in it.
