UV-可见光将Ag（DM）2（DM = 2，5-二甲基-N，N '-二氰基醌二亚胺; DMe-DCNQI）转化为几种具有金属、半导体或绝缘导电性的固体，这取决于照射条件。用Ag L 3 -边XANES测定了各光化学产物中Ag的价态。XANES的结果需要校正的氧化还原机制来解释光诱导的电导率变化的Ag（DM）2光产物。
UV-vis light converts Ag(DM) 2 (DM = 2,5-dimethyl-N,N'-dicyanoquionediimine; DMe-DCNQI) to several solids with metallic, semiconducting, or insulating conductivities depending on the irradiation conditions. Ag valence state in each photochemical product was determined by Ag L 3 -edge XANES. The XANES result requires the correction of the redox mechanism to explain the photoinduced conductivity change of Ag(DM) 2 photoproducts.
