Interfacial behavior of the fourth generation polyamidoamine (G4 PAMAM) dendrimer at the water|1,2-dichloroethane (DCE) interface was studied by the cyclic voltammetry and the potential modulated fluorescence (PMF) spectroscopy. The irregular voltammetric responses were observed at positively polarized interfaces. Cyclic voltammogram was strongly dependent on pH and concentrations of G4 PAMAM dendrimer and organic supporting electrolyte. PMF spectroscopy was successfully used for analyzing the interfacial mechanism of the dendrimer by adding an anionic porphyrin derivative as a fluorescent probe. Results of the PMF measurements demonstrated that G4 PAMAM dendrimer was transferred across the interface accompanied by its adsorption step at pH 7, while, in the alkaline condition, the adsorption process was not apparently involved in the interfacial behavior.
