TY - JOUR AB - A range of dipolar and quadrupolar gold and ruthenium acetylides have been prepared and their electrochemical (Ru complexes) and nonlinear optical properties assessed; electronic communication between the metal centers diminishes as the ?-delocalizable bridge is lengthened and quadratic NLO merit increases on replacing triarylphosphine by trialkylphosphine. One diruthenium example has the largest two-photon absorption cross-section/molecular weight value observed thus far for an organometallic complex.
