Abstract
Low-generation alkynylruthenium dendrimers with arylethynyl branching and spacer units have been synthesized. A "steric control" methodology to rapidly afford the necessary organometallic dendrons has been developed. The dendrimer complexes possess interesting nonlinear optical properties, including very large two-photon absorption cross-sections, the wavelength dependence of which has been examined in one case. They also undergo reversible oxidation in solution, which results in both linear and nonlinear electrochromism.
