Abstract

See full text

Fluorinated cyclopentene moieties and fluorinated cyclopentene functionalized silica materials are provided. The fluorinated cyclopentene functionalized silica materials include a silica material having the fluorinated cyclopentene moiety covalently bonded thereto. Exemplary silica materials include a polysilsesquioxane, a nanosilica, a microsilica, a silica gel, a silica aerogel, or combinations thereof. The fluorinated cyclopentene moieties are based on a modification of perfluorocyclopentene (i.e., 1,2,3,3,4,4,5,5-octafluoro-1-cyclopentene) by nucleophilic substitution with an appropriate nucleophile having a reactive functional group. Methods for preparing fluorinated cyclopentene moieties and the corresponding fluorinated cyclopentene functionalized silica materials are also provided.
