Critical has been understanding the role of intrinsic cyanometalate overlayers in modulating interfacial photoinduced charge transfer processes occuring at the Cd chalconide/aqueous ferri-ferrocyanide interface. Structural and charge transfer studies of (CdFe(CN)(sub 6))(sup 2-/1-) overlayers were undertaken; a picture has evolved which directly links charge transfer mediated cation intercalation processes to surface overlayer crystal structure, and overlayer structure to critical charge transfer parameters.
