摘要
By bathing a smooth and highly [111]-oriented Ag film in a monomeric solution of pseudoisocyanine (1,1'-diethyl-2,2'-cyanine) bromide, we have found a uniform monolayer adsorption of self-assembled two-dimensional J-aggregate. A specific interaction of bromide ions with the Ag (111) surface seemed to be the major driving force for the dye adsorption. The system allows combined conventional spectroscopy and scanning tunneling microscopy studies of adsorbed J-aggregates of cyanine dyes.
