On the Second-Order Nonlinear Optical Structure−Property Relationships of Metal Chromophores

The synthesis and solvent-dependent second-order polarizability, β, responses of three new platinum(II) chromophores are reported. A strong correlation between the metal chromophore electronic structure and the second-order polarizability is observed that substantiates the use of the two-state model to design, optimize, and study new NLO chromophores.
