单核配合物[Co（phen）]的光诱导价态互变异构及其弛豫过程（3，5-DTBSQ）（3，5-DTBCat）]（1）（phen = 1，10-菲咯啉，3，5-DTBSQ = 3，5-二叔丁基半醌，3，5-DTBCat = 3，5-二叔丁基邻苯二酚）的半醌自由基的ESR信号进行了研究，无论是在粉末样品和样品稀释在丁腈或苯玻璃基质。在所有样品中观察到LIVT现象。用双指数拟合方法分析了ESR信号的衰减和玻璃基体中的弛豫过程，表明LIVT过程可能是两步机制。
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.
