Metallodendrimers with ten chiral Ru centers have been prepared in a stereospecific fashion (see picture; •=chiral Ru(diimine) 3 center). These molecules are conformationally rigid and exhibit well‐defined global topologies: some diastereomers exhibit macroscopically chiral structures, others show a disklike topology. This difference in global or tertiary structure is exemplified by differences in their colloidal behavior, as observed in electric birefringence measurements.
