Paper Abstract

Second-order nonlinear optical properties of organic and inorganic materials have been widely investigated. However, it becomes more important to be able to switch the molecules from an 'on' state to an 'off' state, or vise versa. Several switching schemes can be thought of. We will focus our attention to alter the donor properties of metalorganic compounds. Therefore, we will oxidize the metal center of the compound chemically. Since it is more interesting to be able to electrochemically switch the metal center, we developed a combined electrochemistry/hyper-Rayleigh scattering cell to perform in-situ electrochemical switching of the hyper-Rayleigh response.
