Molecular Symmetry and Solution‐Phase Structure Interrogated by Hyper‐Rayleigh Depolarization Measurements: Elaborating Highly Hyperpolarizable <i>D</i>₂‐Symmetric Chromophores

Abstract

Strongly coupled oscillators with D2 and D2d symmetry can act as potent octopolar chromophores with nonlinear optical properties according to Hyper-Rayleigh light-scattering measurements, which demonstrate that small solution-phase structural subpopulations having these symmetries (θ≈−ϕ and θ=−ϕ=|45°|, respectively, for the chromophore shown in the picture) can exhibit exceptional hyperpolarizabilities.
