The second-order hyperpolarizabilities (β) of aromatic sulfonate anions were evaluated by the semiempirical molecular orbital (MNDO) calculation. The sulfonate group show the property of an electron donating group. The μ values of these anions decrease and the β values increase with increasing electron withdrawing ability of substituents at the para position, respectively. Since these anions were found to have comparatively large β and short cutoff wavelength, aromatic sulfonate ions are concluded to be worth investigating as potential chromophores for second-order nonlinear optical materials.
