Representative high-μβ chromophores

Chromophore	μB, 10−48 esu	μβ/MW	Chromophore	μβ, 10−48 esu	μβ/MW

μβ/MW: μ, chromophore dipole moment; β, first molecular hyperpolarizability; and MW, chromophore molecular weight. DR, disperse red; ISX, isoxazolone; TCI, tetracyanoidane; esu, electrostatic units.
