Abstract:

A soluble, oxidatively and thermally very stable alkynylruthenium dendrimer 1,3,5-C6H3(4-C≡C-C6H 4C≡C-trans-[Ru(dppe)2]C≡C-3,5-C 6H3-{4-C≡CC6-H 4C≡C-trans-[Ru(C≡CPh)(dppe)2]} 2)3, containing a large two-dimensional π-delocalized system, has been prepared using an experimentally straightforward convergent synthetic approach. The first third-order nonlinear optical (NLO) measurements of an organometallic dendrimer have been obtained using the Z-scan technique at a wavelength of 800 nm. Progression from 1,3,5-C6H3-(4-C≡CC6H 4C≡C-trans-[Ru(dppe)2]C≡CPh)3 to the dendrimer results in (i) no loss of optical transparency, (ii) an increase in the second hyperpolarizability, γ, which is proportionately greater than either the increase in the number of phenylethynyl groups or the extinction coefficient for the important MLCT band, and (iii) a dramatic enhancement of two-photon absorption.
