A novel octazido substituted nanobuilding precursor, octakis[dimethy(p-azidomethylene)siloxyl]octasilsesquioxane (ODA), was prepared by the conventional diazo-transfer reaction of octakis[dimethy(p-chloromethylene)silyl]octasilsesquioxane (ODC) with NaN3, and its structure was characterized by FT-IR, H-1, C-13, Si-29 NMR and MALDI-TOF MS, respectively. The structural rearrangement of POSS core in the synthesis strategy of ODA developed in this work was effectively prohibited in comparison with traditionary azidization process. The resultant ODA was not only soluble in common solvents such as CHCl3, THF, toluene, DMF and DMSO, but also could effectively serve as a versatile nanobuilding precursor for the architecture of well-defined organic-inorganic hybrids via click chemistry.
