Electrochemical control of the molecular encapsulation behavior and charge transfer reaction of the dendrimer at the liquid/liquid interface

在极化的液/液界面，研究了阴离子荧光染料分子在树枝状大分子中的分子包覆。根据pH条件，阴离子物种被静电结合到树枝状大分子中。光谱电化学分析表明，树枝状大分子与阴离子缔合的界面机理包括转移和吸附过程。此外，在树状大分子的存在下，研究了阴离子锌卟啉与界面疏水猝灭剂之间的非均相光诱导电子转移。树枝状大分子的加入显著提高了光电流响应。

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.
