Chemical States of Ag in Ag(DMe-DCNQI)2 Photoproducts and a Proposal for Its Photoinduced Conductivity Change Mechanism

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 L3-edge XANES. The XANES r...

Description
Summary: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 L3-edge XANES. The XANES result requires the correction of the redox mechanism to explain the photoinduced conductivity change of Ag(DM)2 photoproducts.
