| Research Abstract |
Molecular encapsulation of anionic fluorescent dye molecules in the dendrimer was investigated at the polarized liquid/liquid interface. The anionic species was electrostatically incorporated in the dendrimer depending on the pH conditions. The spectroelectrochemical analysis demonstrated that the interfacial mechanism of the dendrimer associated with anions involves transfer and adsorption processes. In addition, a heterogeneous photoinduced electron transfer between anionic zinc porphyrin and hydrophobic quenchers at the interface was examined in the presence of the dendrimer. The photocurrent response was significantly increased by the addition of the dendrimer.
