Abstract
We study the effect of visible light on chemical waves in thin layers of solution containing the bromate-1,4-cyclohexanedione bubble-free os cillating reaction with added Ru(bpy)(3)(2+), ferroin, or diphenylamin e as the third initial reactant. The light sensitivity was found to be much stronger in the ferroin-catalyzed system than in the Ru(bpy)(3)- catalyzed one, contrary to observations in the analogous reactions wit h malonic acid as the reductant. The combination of photosensitivity a nd absence of bubbles makes these reactions convenient tools for study ing waves and patterns in reaction-diffusion systems.
