Research Themes
Spectroelectrochemical Study of Charge Transfer Mechanism at Liquid/Liquid Interfaces
The interfacial behavior of ionic dyes at the polarized liquid/liquid interface is studied by spectroelectrochemical techniques. By analyzing the appropriate optical signal instead of the overall current responses, the interfacial behavior of the target dye species could be studied in the absence of the interference with non-chromophoric species. A lock-in detection of ac-modulated optical signals under the potential-modulation superimposed on a linear potential sweep improves the sensitivity and the selectivity to the interfacial phenomena of dye species.
Potential-modulated fluorescence (PMF) spectroscopy has been applied for the ion-transfer reaction across the liquid/liquid interface. The high sensitivity of PMF spectroscopy to interfacial phenomena, especially adsorption, has allowed us to investigate the various fluorescent species, such as porphyrin, xanthene, and pyrene derivatives. The combination of PMF spectroscopy and conventional electrochemical techniques could uncover the interfacial adsorption and transfer mechanisms.
Dynamic Control of Ion Transfer Reaction through Association with Dendritic Polymers at Liquid/Liquid Interfaces
The phase transfer feature of chemical species is mainly attributed to their functional groups and charged states. Dendritic polymers such as dendrimer can associate with ionic species through the encapsulation into its internal cavity and the interaction with its terminal functional groups.
We apply the dendritic polymer as functional molecular carrier to control the ionic distribution and reactivity at liquid/liquid interfaces and on membrane surfaces. It has been demonstrated that ionic species including functional dyes, drugs, bio-related substances associate with dendritic polymers and their charge transfer mechanism are controllable by tuning external stimuli. In particular, the potential- and pH-responsive drug loading and release on biomimetic membrane surfaces have promise as functional drug delivery systems.
Photoelectrochemical reactivity of metal nanoparticles at liquid/liquid interfaces
In a heterogeneous photoinduced electron transfer reaction between hydrophilic dyes and lipophilic quenchers across a liquid/liquid interface, the hydrophile-lipophile intermediate ion pair can be formed only in the interfacial region. The product-separation process of the intermediate takes place effectively at the interface.
Recently, we have demonstrated that a photocurrent arising from the photoreduction of metalloporphyrin is significantly enhanced in the presence of gold nanoparticles (Au-NPs). The photocurrent enhancement is dependent on the concentration of Au-NPs, the excitation wavelength, and the polarization angle of the excitation light, respectively. The photocurrent enhancements could be correlated with Au-NPs acting as sensitizers involving the localized surface plasmon (LSP) effect to improve the photoreaction yield. We further investigate the photoreactivity of metal nanoparticles, e.g. Au-NPs, gold core-silver shell nanoparticles etc., electrochemically adsorbed at the liquid/liquid interface.
