摘要
Fluorinated polyhedral oligomeric silsesquioxane (F-POSS) compounds were prepared by employing a facile, corner-capping methodology. Using this modular approach, fluorocarbons with varying degree of fluorine content and architecture were installed on the POSS cage of a partially condensed trisilanol. The melting properties of the F-POSS derivatives showed various influence by Si center dot center dot center dot F contacts via intermolecular packing assembly. All F-POSS compounds were characterized by H-1, C-13, F-19, and Si-29 NMR spectrometry, X-ray crystallography, thermal and elemental combustion analysis.
