✦ Synopsis

The u&(2,2'-bipyridine)ruthenium(II)-catalyzed minimal bromate oscillator is shown to exhibit the chemical oscillation similarly to the system with other catalysts. The photoresponse of the minimal oscillator has been investigated for the first time to show both induction and inhibition of sustained oscillations. It has been found that [ Br -] tends to decrease not only in the photoinduction but also in the photoinhibition of chemical oscillation, in contrast to the previous view for the photoinduced pattern formation in the full Belousov-Zhabotinsky system. This result may require more detailed investigation for the latter system.

## Abstract Perturbation of the tris(2,2′‐bipyridine)ruthenium(II) [Ru(bpy)~3~^2+^]‐catalyzed Belousov–Zhabotinsky (BZ) oscillating chemiluminescence (CL) reaction induced by l‐cysteine was observed in the closed system. It was found that the CL intensity was decreased in the presence of l‐cysteine
