Second harmonic generation (SHG) was used to carry out an in situ study of the potential-induced reconstruction of an Au(110) single crystal electrode in an aqueous solution of 0.01 M HClO4. In this study, we found that the symmetries of the surface susceptibility of the reconstructed and the unreconstructed Au(110) surfaces have a large component of threefold symmetry. A detailed analysis shows that both surfaces have an overall Cs symmetry giving one-, two-, and threefold symmetries for the surface susceptibility. However, another, different, source of threefold symmetry, perpendicular to the first, is needed to fit the data. We suggest that this extra source of threefold symmetry is due to the (111) microfacets that are present on the open (110) surface. Keywords: electrochemistry, single crystal, reconstruction, second harmonic generation spectroscopy.

Property A

NIR-PDT strategy was introduced by employing a nonlinear optical conveyor bearing strong second-harmonic generation (SHG) property. A biocompatible micellic system co-delivered the conveyor and photosensitizer for in situ NIR-PDT.
