Abstract

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…F contacts via intermolecular packing assembly. All F-POSS compounds were characterized by 1H, 13C, 19F, and 29Si NMR spectrometry, X-ray crystallography, thermal and elemental combustion analysis.
