The silsesquioxane-tethered fluorene ligand (c-C5H9)(7)Si8O12CH2-9-Flu(H) and zirconocene complexes thereof, C5H3(SiMe3)(2)[(c-C5H9)(7)Si8O12CH2-9-Flu]ZrCl2 and [(c-C5H9)(7)Si8O12CH2-9-Flu](2)ZrCl2, have been used to optimize the synthetic strategies for the corresponding silica-tethered zirconocenes and to study their steric and electronic properties.
