silica nanospheres are prepared through the co-assembly of chiral (4-(trimethoxysilyl)ethyl)phenylsulfonyl-1,2-diphenylethylene-diamine and tetraethoxysilane followed by complexation with an organoruthenium complex. Structural analysis and characterization disclose its well-defined single-site organoruthenium active center, and electron microscopy images reveal its uniformly distributive, mesostructured
