Y(C6H5SO3)3·9H2O: strategic integration of ligand substitution and π-conjugated group linkage in sulfates for enhanced ultraviolet nonlinear optical properties

By employing the strategic integration of ligand substitution and π-conjugated group linkage, the first UV NLO benzenesulfonate, i.e. Y(C 6 H 5 SO 3 ) 3 ·9H 2 O, have been synthesized and reported with comprehensive performance.
