Paper Abstract

A series of novel metal-organic in-plane complexes trans- (formula available in paper) have been investigated using the hyper-Rayleigh scattering technique. Like other in-plane complexes reported recently they exhibit very large and tunable static first hyperpolarizabilities which are associated with intense visible metal-to-ligand charge-transfer excitations. Moreover, a good correlation was found between the hyperpolarizabilities and the electrochemical properties of the complexes. Furthermore, the effect of the oxidation state of the metal upon the molecular optical nonlinearity has been investigated. Chemical oxidation of the metal is proven to be an excellent tool to reversibly switch the molecular first hyperpolarizabilities of the trans- substituted ruthenium complexes.
