Abstract

The classical molecular engineering schemes based on quasi one-dimensional dipolar charge transfer are enlarged to molecules with two- or three-dimensional contributions of octupolar origin. We report here a large increase in quadratic hyperpolarizability β values (up to 2.10^-27 e.s.u.) of chiral ruthenium complexes upon successive complexation by one, two and three bipyridine derivatives. A strong metal-to-ligand charge transfer is evidenced from comparison of the experimental β value of the three-substituted complex with that deduced from a simple additive model of metal-ligand interaction
