Abstract

The second-order hyperpolarizabilities (β) of ionic species of sodium p-toluenesulfonate (pTSNa) and its corresponding neutral derivative methyl p-toluenesulfonate (pTSMe) in methanol were evaluated to be 2.2 × 10–29 and 1.2 × 10–29 esu, respectively, using the hyper Rayleigh scattering method at 1064 nm. Since ionic pTSNa has short cutoff wavelength of 280 nm as well as comparatively large β value, i.e., about twice that of neutral pTSMe and about two-thirds that of p-nitroaniline, aromatic sulfonate ions are concluded to be worth investigating as potential chromophores for second-order nonlinear optics.
