Research works on the self-organization phenomena in chemical systems are reviewed with particular emphasis on their response to the photo-irradiation, for which most of the works have been performed in the author’s laboratory. In the present review, a brief survey is given for the recent developments of research on the self-organization phenomena observed in dark. Then, the determination of action spectra for the photo-irradiated self-organizing chemical systems is described with a few examples, together with a discussion on the advantages of employing the irradiated light intensity as a control parameter. Experimental results for the chemical systems under the stationary and pulse light irradiation are summarized and discussed for the redox oscillators including the Belousov-Zhabotinsky and the Briggs-Rauscher systems and their variations. Discussions are also given for various types of pH oscillators under photo-irradiation. Finally, experimental observations on chaos and multistability, the most characteristic features in the field of self-organizing chemical systems, are surveyed and discussed. Possibility of the photo-control of chaos and multistability is discussed with examples of the Briggs-Rauscher system and of the pH oscillator system, H2O2-SO32--Fe(CN)64--HCO3-.
