Aromatic thiolate anions ArS
− are expected from a semi-empirical calculation with PM3 parametrisation of the MNDO Hamiltonian, to possess higher intrinsic polarizabilities than the parent neutral thiols ArSH. Noncentrosymmetric thiolate salts have been synthesized by the reaction of ArSH with chiral amines and investigated for their second-order (through frequency doubling) and third-order (through degenerate four-wave mixing technique) nonlinear optical properties.
