N2 - Light-induced valence tautomerism (LIVT) and the relaxation process of a mononuclear complex, [Co(phen)(3,5-DTBSQ)(3,5-DTBCat)] (1) (phen = 1,10-phenanthroline, 3,5-DTBSQ = 3,5-di-tert-butyl-semiquinone, 3,5-DTBCat = 3,5-di-tert-butyl-catechol) were investigated by monitoring the ESR signal of the semiquinonate radical both in powder sample and in the sample diluted in butyronitrile or benzene glass matrix. LIVT phenomena were observed in all samples. The ESR signal decay and the relaxation in the glass matrixes were well analyzed by double exponential fitting, indicating the possibility of two-step mechanism in the LIVT process.
