Abstract

The new organometallic compounds [{(E)-2-SC₄H ₃CH=CHC₆H₄-X-p}Ru(C₆Me ₆)][CF₃SO₃]₂ (X = MeO (1), Me (2), H (3), Br (4), NO₂ (5)), bearing a (thiophene)Ru(C₆Me ₆)²⁺ fragment in the end group, have been prepared for nonlinear optical chromophores, and their hyperpolarizabilities have been measured by the HRS method. The static hyperpolarizability (β₀) values of the complexes increase as the electron-acceptor power of the substituent X increases (MeO < Me < H < Br < NO₂). Replacement of hexamethylbenzene with pentamethylcyclopentadienyl resulted in [{(E)-2-SC₄H₃CH=CHC₆H₄-NO ₂-p}]Ru(C₅Me₅)]CF₃SO₃ (7), showing a significant increase in the hyperpolarizability. The substituent effects on β₀ were studied by time-dependent DFT calculations.
